Why does boric acid have a lower lethal dose than borax? because acid is poorly soluble in water and it should be the other way around
as far as I know, boric acid and borax are practically harmless to humans
nevertheless, they also have toxicity, like many substances
Wonder if it can be something to do with electeophylicity
@chaoticgood Okay, usually the toxicity of compounds is directly related to the ability to dissolve and be absorbed with water in the digestive tract.
Not only solubility plays important role in the process, reactivity is important too
It's tough to argue with that, but also they are two different properties of substance
@chaoticgood Usually, for oral exposure to the body, a dependence is drawn out that the greater the solubility, the greater the toxicity, and vice versa. Remember, for example, soluble barium salts are toxic, but BaSO4 is safe
I'm not against this statement. My idea is that it's not the only parameter
@chaoticgood What other parameters should be considered for example?
There is more (w/w%) boron in boric acid than in borax. The form is pretty the same, B(iii) neighboured by oxygen, so only the mass fraction is matter.
