Polyprotic Acids

Our understanding of diprotic acids and bases can be used to understand polyprotic acids and bases.&#160;

Ka1 is much larger than Ka2 and Ka3<.sub>.

The extent of successive ionizations does decrease.

Ka1 = Kw

Correct, the magnitude of Ka1 will vary with the strength of the acid.

We can assume [H2PO4&#8722;] = [H3O+].

This relation is valid since most of H3O+ comes from the initial acid ionization step.

[HPO42&#8722;] &#8776; Ka2

The protons are removed from the polyprotic acid in a stepwise fashion.

 Review the properties of acids that can undergo successive ionization reactions. 

Which of the following statements about the ionization of a polyprotic acid, such as H3PO4, is false?

Polyprotic Acid Practice

H2NO2+ + OH&#8722;

HNO2 is a stronger acid than water.

NO2&#8722; + H3O+

One substance will lose a proton and the other will gain a proton.

NO2&#8722; + OH&#8722;

NO2 + H3O+

When an acid donates a positive proton, it attains a more negative charge.

HNO2 is a weak acid. Acids will donate a proton to water.

Predict the products of the reaction below: HNO2 + H2O &#8646;
