Question

Complete the following double displacement reactions
1. KHO + H2SO4—
2. NaOH + HCI—
3. Al2 (SO4)3 + NaOH—
4. BaCL2 + Na2SO4—
5. PbSO4 + Na2CO3--

Answer 1

Answer:

1. 2KHO+H2SO4=2H2O+K2SO4

2. NaOH+HCI=NaCl+H2O

3. Al2(SO4)3+6NaOH=2Al(OH)3+3Na2SO4

4. BaCL2+Na2SO4=BaSO4+2NaCl

5. PbSO4+Na2CO3=PbCO3+Na2SO4

Answer 2

Answer:

1. KHO + H2SO4 —

2KHO + H2SO4  = 2H2O + K2SO4

2. NaOH + HCI —

NaOH + HCI = NaCl + H2O

3. Al2 (SO4)3 + NaOH —

Al2(SO4)3 + 6NaOH = 2Al(OH)3 + 3Na2SO4

4. BaCL2 + Na2SO4 —

BaCL2 + Na2SO4 = BaSO4 + 2NaCl

5.PbSO4 + Na2CO3 —

PbSO4 + Na2CO3 = PbCO3 + Na2SO4
