KH2PO4水溶液的质子条件式为:[H+] = [H2PO4 -] + [HPO42-] + 2[PO43-] + [OH-] -[H 3PO 4]。
举一反三
- KH2PO4水溶液的质子条件式为:[H+]+[H3PO4]=[H2PO4-]+[HPO42-]+2[PO43-]+[OH-]
- HPO42-其水溶液的质子条件式是[H+]+[H3PO4]+[H2PO4- ] = [OH-]+[PO43-] 。
- KH2PO4水溶液的质子条件为:[H+]+[H3PO4] = [H2PO4-] + [HPO42-] + 2[PO43-] + [OH-]
- NaH2PO4水溶液的质子条件式为:[H+]= [OH-] + [HPO42-] +[PO43-]-[H3PO4]
