Do you have any advice on understanding conjugate acids and bases? They get more confusing the more I try to learn them _(:3

Heya!

Okok so for acids and bases we have two definitions, as if chemistry isn’t already confusing enough. 

* Before I start this is a very very sarcastic post intended to make chemistry a little more fun, don’t be offended

** I have the most respect for Lewis, Bronsted and Lowry, they’ve accomplished more than I ever will again this post is meant to be taken lightly

First up we have Lewis! Aka founder of the Lewis Dot Diagrams, aka the bane of my high school life. Lewis defined an acid to be an electron-pair acceptor (eg. BF3) , and a base to be an electron-pair donor (eg. OH-). This basically means that the species are electron-deficient and electron-rich, respectively. 

Lewis Acid: Electron-pair acceptor

Lewis Base: Electron-pair donor

But because it’s 1923 and old white aristocrats have nothing better to do but argue with each other and one each other up, the Bronsted-Lowry pair come along and make a second definition for acids and bases. This is the definition that we use for conjugate acid-base pairs! 

B-L Acid: Hydrogen ion donor

B-L Base: Hydrogen ion acceptor

Nice! Now we can define a reaction between a B-L acid and base to be:

HA + B –> A- + BH+

In a reaction between a B-L acid and base, the acid will donate a proton to the base to form their respective conjugate products. Notice that A- is the proton-deficient conjugate form of HA, and B is the proton-deficient conjugate form of BH+. 

By the Webster online dictionary, a conjugate is a pair of species. We can say that HA and A- is a pair, or a conjugate, as they differ by one proton. By donating one H+ to the base, HA loses the H to form A-. 

So HA and A- are conjugate pairs. If you go back to the B-L definition of an acid and base, an acid is a hydrogen ion donor, and we’ve already defined HA to be the donor. That means it’s the acid of this conjugate-pair. On the other hand, A- is hydrogen-ion-deficient; it can only accept hydrogen ions. By the B-L definition, A- is the conjugate base. 

When you look at the equation, “HA + B –> A + BH+” can you see that there is an acid and a base on both sides of the equation? HA donates a proton to B (acid), and B accepts the proton (base). Similarly on the other side, BH+ has an excess of protons and donates (acid) it to A. A, being proton-deficient, accepts the proton (base) donated by BH+. 

The conjugate part of conjugate acid-base pair is really just a technical definition. It’s a pair of species that differ by one proton. Some examples would be: HCl and Cl-, HOH and OH-, NH4+ and NH3. 

I hope this helps! Feel free to message me again if it doesn’t :)

writing adult emails is awful

its like

hi [name of person], 

this formatting is making me uncomfortable but I have to tell you something / ask you something that is vital to my career as a student. 

I re-read and edited that sentence for an hour, but you’ll probably just glance over it for half a second.

thanks!

I have a stock format and structure I use.

Dear Person I am Writing To:

This is an optional sentence introducing who I am and work for, included if the addressee has never corresponded with me before. The second optional sentence reminds the person where we met, if relevant. This sentence states the purpose of the email.

This optional paragraph describes in more detail what’s needed. This sentence discusses relevant information like how soon an answer is needed, what kind of an answer is needed, and any information that the other person might find useful. If there’s a lot of information, it’s a good idea to separate this paragraph into two or three paragraphs to avoid having a Wall of Text.

If a description paragraph was used, close with a restatement of the initial request, in case the addressee ignored the opening paragraph.

This sentence is just a platitude (usually thanking them for their time) because people think I’m standoffish, unreasonably demanding, or cold if it’s not included.

Closing salutation,

Signature.

People always ask me how I can fire off work emails so quickly. Nobody has figured out yet that it’s the same email with the details changed as needed.

SOME SUGGESTIONS FOR WRITING YOUR PHILOSOPHY PAPER

Organize carefully. Before you start to write make an outline of how you want to argue. There should be a logical progression of ideas - one that will be easy for the reader to follow. If your paper is well organized, the reader will be led along in what seems a natural way. If you jump about in your essay, the reader will balk. It will take a real effort to follow you, and he or she may feel it not worthwhile. It is a good idea to let your outline simmer for a few days before you write your first draft. Does it still seem to flow smoothly when you come back to it? If not, the best prose in the world will not be enough to make it work.

Use the right words. Once you have determined your outline, you must select the exact words that will convey your meaning to the reader. A dictionary is almost essential here. Do not settle for a word that (you think) comes close to capturing the sense you have in mind. Notice that “infer” does not mean “imply”; “disinterested” does not mean “uninterested”; and “reference” does not mean either “illusion” or “allusion.” Make certain that you can use “its” and “it’s” correctly. Notice that certain words such as “therefore,” “hence,” “since,” and “follows from” are strong logical connectives. When you use such expressions you are asserting that certain tight logical relations hold between the claims in question. You had better be right. Finally, check the spelling of any word you are not sure of. There is no excuse for “existance” appearing in any philosophy essay.

Support your claims. Assume that your reader is constantly asking such questions as “Why should I accept that?” If you presuppose that he or she is at least mildly skeptical of most of your claims, you are more likely to succeed in writing a paper that argues for a position. Most first attempts at writing philosophy essays fall down on this point. Substantiate your claims whenever there is reason to think that your critics would not grant them.

Give credit. When quoting or paraphrasing, always give some citation. Indicate your indebtedness, whether it is for specific words, general ideas, or a particular line of argument. To use another writer’s words, ideas, or arguments as if they were your own is to plagiarize. Plagiarism is against the rules of academic institutions and is dishonest. It can jeopardize or even terminate your academic career. Why run that risk when your paper is improved (it appears stronger not weaker) if you give credit where credit is due? That is because appropriately citing the works of others indicates an awareness of some of the relevant literature on the subject.

Anticipate objections. If your position is worth arguing for, there are going to be reasons which have led some people to reject it. Such reasons will amount to criticisms of your stand. A good way to demonstrate the strength of your position is to consider one or two of the best of these objections and show how they can be overcome. This amounts to rejecting the grounds for rejecting your case, and is analogous to stealing your enemies’ ammunition before they have a chance to fire it at you. The trick here is to anticipate the kinds of objections that your critics would actually raise against you if you did not disarm them first. The other challenge is to come to grips with the criticisms you have cited. You must argue that these criticisms miss the mark as far as your case is concerned, or that they are in some sense ill-conceived despite their plausibility. It takes considerable practice and exposure to philosophical writing to develop this engaging style of argumentation, but it is worth it.

Edit boldly. I have never met a person whose first draft of a paper could not be improved significantly by rewriting. The secret to good writing is rewriting - often. Of course it will not do just to reproduce the same thing again. Better drafts are almost always shorter drafts - not because ideas have been left out, but because words have been cut out as ideas have been clarified. Every word that is not needed only clutters. Clear sentences do not just happen. They are the result of tough-minded editing.

What I mean: Sometimes I try to tell the computer to do something and I cry when it doesn't work.
