2 NaOH + H2SO4 = Na2SO4 + 2 H2O

Al(OH)3 + 3 HCl = AlCl3 + 3 H2O

Ca(OH)2+NaOH = X

6 KOH + P2O5 = 2 K3PO4 + 3 H2O

FeCl3 + 3 NaOH = Fe(OH)3 + 3 NaCl

Ca(OH)2 + K2CO3 = 2 KOH + CaCO3

2 NaOH + BaCl2 = Ba(OH)2 + 2 NaCl

Ca3(PO4)2 + 6 KOH = 3 Ca(OH)2 + 2 K3PO4

1.Na2SO4+H2O

2.AlCl3+H2O

3.Ca(OH)2+NaOH
