Theoretical inorganic chemistry pH of aqueous solutions of hypophosphites

I've only seen such salts studying inorganic chemistry, specifically phosphorous properties. Quite uncommon substances 

@chaoticgood Good reducing agents, unstable during storage therefore

@argentum yeah, make sense. In what field are they used? Synthesis, production?

@chaoticgood Chemical deposition of metal films from their salts on various surfaces

It's a pity that no one answered the question, but it is quite interesting

By the way, an interesting fact is that the H₃PO₂ and H₃PO₃ acidity constants are quite close and phosphites are hydrolyzed, unlike hypophosphites

pKa H3PO3= 1,51

pKa H3PO2= 1,23

@argentum What is the reason for such effect?

@chaoticgood What exactly is the effect?

@argentum Similar acidity constants 

@chaoticgood I don’t know, I’m already citing their data, and salts have different hydrolysis

@argentum Where did you find such information about the hydrolysis of hypophosphite salts of alkaline and alkaline earth metals?

You have given the acid constants, which do not quite reflect the degree of acid dissociation, namely their nature. Please give the dissociation constants of these acids.

@damiryagudin I didn’t understand you, acidity constants reflect their dissociation constants
