okay since you asked! :D! i like chemistry a lot more then biology anyway. Here’s the most efficient way to diffuse a wild bakugou!
Sodium hydroxide completely cleaves nitroglycerin because nitroglycerin is a nitrate ester. So not only is it safer then aluminum powder (which has been proposed by some fans), it actually gets rid of the substance instead of absorbing it and making it worst.
In theory it’ll completely cleave the nitroglycerin on a molecular level and basically disable Bakugou’s explosions until he sweats more nitroglycerin then the sodium hydroxide could neutralize. Technically what he sweats isnt pure nitroglycerin (it’s described as “nitroglycerin-like”), so theres some margin of error. Below i’ve measured how many milliliters of sweat he used to destroy ochako’s attack in the sports festival, the biggest explosion he can make without his gauntlets.
This math is coming from one stick of dynamite containing 76 grams of nitroglycerin, and 76 grams of nitroglycerin can reach a blast radius of about 1 cubic meter, so you’ll need about 300ml to blow up a diameter of a football field. Granted it may not be POWERFUL enough to do any damage, but the explosion would cover that volume and there would be considerable force. The magic of anime makes Bakugou’s explosions powerful enough, so I don’t really mind. This is assuming the stadium used in the sports festival meets standard 100 meters used in most sports.
So with these measurements it’ll take 300ml of pure nitroglycerin (UNLIKELY as its unstable in that form without additional compounds) so with a margin of error its about 500ml of Bakugou’s sweat to blow up a volumetric length of 100m cubed (considering the force behind the explosion I went a little higher then my earlier estimate of 400ml). But there’s a little kink in this- Nitroglycerin is somewhat stable at regular temperatures but usually explodes at 122°F (50°C)
The rise in temperature may come from an element not present in most people’s analysis of his quirk- barium, sodium, and potassium.
His dad’s quirk is classified as the “ability to rapidly oxide his sweat.” Combined, barium, sodium and potassium are some of the most explosive prone elements when exposed to peroxides. Hydrogen peroxide is produced naturally in the body, so with the ability to combine that with sweat filled with one of those three elements can make sparks and small explosions. Perhaps not enough to do a lot of damage on its own, but combined with another aspect of Bakugou’s quirk it can do AMAZING damage that i’ll explain now!
So Bakugou’s sweat is a two part deal- his “fuel” and his “ignition.” Nitroglycerin is his “fuel”- a semi-stable sweat compound that is only dangerous when either friction is used or when temperatures of 122°F are reaches. And the “ignition”- rapidly oxidizing the sodium/potassium/barium compounds in his sweat to reach temperatures high enough to cause a chain reaction.
Keep in mind, I measured Bakugou’s BIGGEST explosion without his gauntlets (can’t get reliable measurements when he uses his gauntlets) so we can assume 1000ml of sodium hydroxide or 1000 cubic centimeters of sodium hydroxide powder can completely neutralize Bakugou under the right conditions.
Nitroglycerin also has a reputation of hanging around and getting more explosive as time goes on, so any of Bakugou’s clothing would have to be chemically bathed in a sodium hydroxide solution before being washed. Unless BNHAverse has adaptive clothing that can absorb one of the most explosive compounds on earth without major side effects, which is probably the case considering Bakugou’s hero costume does exactly that.
Also I like to think that anytime Momo is fed up with Bakugou’s bullshit she makes a bunch of sodium hydroxide and dunks him in the sauce. get sodium hydroxided idiot.
