Question

напишите ур-ия реакций нейтрализации,протекающих между следующими веществами:

1)H3PO4;  2) KOH;  3)CA(OH)2; 4) HCL; 5) H2SO4; 6)NаOH

 

 

Answer 1

1) 2H3PO4 + 3Ca(OH)2 = Ca3(PO4)2 + 6H2O

2)H3PO4 + 3NaOH = Na3PO4 + 3H2O

3)H3PO4 + 3KOH = K3PO4 + 3H2O

4) KOH + HCl = KCl + H2O

5)2KOH + H2SO4 = K2SO4 + 2H2O

6)Ca(OH)2 + 2HCl = CaCl2 + 2H2O

7)Ca(OH)2 + H2SO4 = CaSO4 + 2H2O

8)HCl + NaOH = NaCl + H2O

9)H2SO4 + 2NaOH = Na2SO4 + 2H2O

Answer 2

h3po4+3koh=k3po4+3h2o

h3po4+3ca(oh)2=ca3(po4)2+3h2o

h3po4+3naoh=na3po4+3h2o

hcl+koh=kcl+h2o

2hcl+ca(oh)2=cacl2+2h2o

hcl+naoh=nacl+h2o

h2so4+2koh=k2so4+2h2o

h2so4+ca(oh)2=caso4+2h2o

h2so4+2naoh=na2so4+2h2o
