5. A few drops of iodine solution were added to rice water. The solution turned blue - black in color. What does this indicates?

Answer 1

2CH3COOH+2Na =2CH3OONa+H2O

2CH3COOH+Na2CO3=2CH3COONa+CO2+H2O

CH3COOH +NaOH = CH3COONa +H2O

Answer 2

Answer:

Explanation:

2CH3COOH+2Na =2CH3OONa+H2O

2CH3COOH+Na2CO3=2CH3COONa+CO2+H2O

CH3COOH +NaOH = CH3COONa +H2O
