Question

Dokończ równania reakcji (także jonowe):

1. HCOOH + Al ->

2. HCOOH + CaO ->

3. CH₃COOH + K₂O ->

4. CH₃COOH + Ba(OH)₂ ->

Jonowe, to chodzi o to:

HCOO⁻ + H⁺ itd...

Daję naj.

Answer 1

1. 6HCOOH + 2Al ->2(HCOO)3Al+3H2
6HCOO- +6H+ +2Al ---> 6HCOO- +2Al3+ +3H2
6H+ +2Al --->2Al3+ +3H2

2. 2HCOOH + CaO ->(HCOO)2Ca+H2O
2HCOO- +2H+ +CaO --->2HCOO- +Ca2+ +H2O
2H+ +CaO--->Ca2+ +H2O

3. 2CH₃COOH + K₂O -> 2CH3COOK+H2O
2CH3COO- +2H+ +K2O --->2CH3COO- +2K+ +H2O
2H+ +K2O--->2K+ +H2O

4. 2CH₃COOH + Ba(OH)₂ -> (CH3COO)2Ba+2H2O
2CH3COO- +2H+ +Ba2+ +2OH- --->2CH3COO- +Ba2+ +2H2O
2H+ +2OH- --->2H2O
