Using In HPLC buffers why KH2PO4 is called monobasic. is it because of K+ or any theory

Monobasic potassium hydrogen phosphate is KH2PO4
Dibasic potassium hydrogen phosphate is K2HPO4

It basically has to do with how many equivalents of acid will react with the substance.  Monobasic potassium hydrogen phosphate can react with only one equivalent of acid:

KH2PO4 + HCl --> H3PO4 + KCl

whereas dibasic potassium hydrogen phosphate can react with two equivalents of acid:

K2HPO4 + 2HCl --> H3PO4 + 2KCl
