Verified answer
NaH2PO4 + 2NaOH = Na3PO4 + 2H2ONa[+] + H2PO4[-] + 2Na[+] + 2OH[-] = 3Na[+] + PO4[3-] + 2H2O
H2PO4[-] + 2OH[-] = PO4[3-] + 2H2O
NH4OH + HNO3 = NH4NO3 + H2O
NH4[+] + OH[-] + H[+] + NO3[-] = NH4[+] + NO3[-] + H2O
H[+] + OH[-] = H2O
Al(OH)2Br + 2HBr = AlBr3 + 2H2O
Al(OH)2[+] + Br[-] + 2H[+] + 2Br[-] = Al[3+] + 3Br[-] + 2H2O
Al(OH)2[+] + 2H[+] = Al[3+] + 2H2O
Sr(OH)2 + 2KOH = K2[Sn(OH)4]
Sr[2+] + 2OH[-] + 2K[+] + 2OH[-] = 2K[+] + [Sn(OH)4] [2-]
Sr[2+] + 2OH[-] + 2OH[-] = [Sn(OH)4] [2-]
1)MgCO3+CuSO4
2)CH3COONH4+HJ
3)ZnCl2+K2SO3
4)Ba(NO3)2+FeBr3
5)Sn(NO3)2+H2O
6)K2CO3+H2O
7)Al2S3+H2O
