Na2HPO4水溶液的质子条件式PBE正确的是( )
A: [H+] + [H2PO4- ]+[H3PO4] = [OH-] +[PO43-]
B: [H+] + [H2PO4- ]+2[H3PO4] = [OH-] +[PO43-]
C: [H+] +2[H3PO4] = [OH-] +[PO43-]+ [H2PO4- ]
D: [H+] + [H2PO4- ] = [OH-] +[PO43-]
A: [H+] + [H2PO4- ]+[H3PO4] = [OH-] +[PO43-]
B: [H+] + [H2PO4- ]+2[H3PO4] = [OH-] +[PO43-]
C: [H+] +2[H3PO4] = [OH-] +[PO43-]+ [H2PO4- ]
D: [H+] + [H2PO4- ] = [OH-] +[PO43-]
举一反三
- 下列有关Na2HPO4在水溶液中质子条件的叙述,哪个是正确的?（ ） A: [H2PO4-] + [H3PO4] + [H+] =3 [PO43-]+ [OH-] B: 2[H2PO4-] + 3[H3PO4] + [H+] = [PO43-]+ [OH-] C: 3[H2PO4-] + 2[H3PO4] + [H+] = [PO43-]+ [OH-] D: [H2PO4-] + 2[H3PO4] + [H+] = [PO43-]+ [OH-]
- Na2HPO4水溶液的质子条件式为 A: [H+]+[H2PO4-]+2´[H3PO4]=[OH- ]+[PO43-] B: [H2PO4-]+2´[H3PO4]=[PO43-] C: [H+]+[H2PO4-]+[H3PO4]=[OH- ]+[PO43-] D: [HPO42-]+[H2PO4-]+2´[H3PO4]=[PO43-]
- Na2HPO4的质子条件式是（） A: [H+]+ [H3PO4]= [HPO42-] + 2 [PO43-] +[OH-] B: [H+]+ [H3PO4]= [H2PO4-] + [PO43-] +[OH-] C: 2 [H3PO4] + [H2PO4-]+ [H+]= [PO43-] +[OH-] D: [H+]+ [H3PO4]= [HPO42-] + 2 [PO43-]
- (NH4)2HPO4水溶液的质子条件式（PBE）正确的是（ ）。 A: [H+]+[H2PO4-]+[H3PO4] = [OH-]+[NH3] +[PO43-]； B: [H+]+[H2PO4-]+2[H3PO4] = [OH-]+[NH4+]+[PO43-]； C: [H+]+[H2PO4-]+2[H3PO4] = [OH-]+[NH3] +[PO43-]； D: [H+]+[H2PO4-]+[H3PO4] = [OH-]+[NH3] +2[HPO42-]。
- (NH4)2HPO4水溶液的质子条件式（PBE）为（ ）。 A: [H+]+[H2PO4-]+[H3PO4] =[OH-]+[NH3] +[PO43-]； B: [H+]+[H2PO4-]+2[H3PO4] =[OH-]+[NH4+] +[PO43-]； C: [H+]+[H2PO4-]+2[H3PO4] =[OH-]+[NH3] +[PO43-]； D: [H+]+[H2PO4-]+[H3PO4] =[OH-]+[NH3] +[HPO42-]。
