Explanation / Answer

part C:

HPO22- is a weak base which takes a H+ ion,

HPO22- + H+ ---> H2PO2- which is its conjugate acid.

part D;

Y- is the strongest base so its conjugate acid will be the weakest so HY will be the weakest acid.

Z- is the weakest base so its conjugate acid will be the strongest so HZ will be the strongest acid,

thus from strongest to weakest

HZ>HX>HY
