What is the Ka value of h2po4?

Question: Ka of H3PO4= 7.5 X 10^-3 Ka of H2PO4= 6.2 X 10^-8 Ka of HPO4= 4.8 X 10^-13 Both of these solutio Both of these solutions are basic since potassium comes from KOH, which is a strong base and the anions are weak acids.

Beside this, what is the Ka of hno2?

Nitric acid, HNO2 is a weak acid with Ka= 4.5 x 10-4. It dissociates according to:
HNO2 (aq) <--> H+ (aq) + NO2- (aq)
a.)

Which acid is strongest and why?

The carborane superacid H(CHB11Cl11), which is thousand times stronger than the strength of sulfuric acid, is entirely non-corrosive, whereas the weak acid hydrofluoric acid (HF) is corrosive and can dissolve, among other things, glass and most metals.

What is the Ka in chemistry?

An acid dissociation constant, Ka, (also known as acidity constant, or acid-ionization constant) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction known as dissociation in the context of acid–base reactions.
