Question : 8 of 11

Marks: +1, -0

Write three different chemical reactions showing the conversion of ethanoic acid to sodium ethanoate. Write balanced chemical equation in each case. Write the name of the reactants and the products other than ethanoic acid and sodium ethanoate in each case.

Solution:

(i)

{2 {\CH}_2 {\COOH}}↙{\text "Ethanoic acid"}+ {{\Na}_2 {\CO}_3 }↙{\text "Sodium carbonate"}→ {2 {\CH}_3 {\COONa}}↙{\text "Sodium ethanoate"}+{ {\H}_2 {\O}}↙{\text "Water"}+ {{\CO}_2 ↑}↙{\text "Carbondioxide"}

(ii)

{{\CH}_2 {\COOH}}↙{\text "Ethanoic acid"}+{ {\NaOH} }↙{\text "Sodium hydroxide"}→ {{\CH}_3 {\COONa}}↙{\text "Sodium ethanoate"}+{ {\H}_2 {\O}}↙{\text "Water"}+ {{\CO}_2 ↑}↙{\text "Carbondioxide"}

(iii)

{{\CH}_3 {\COOH}}↙{\text "Ethanoic acid"}+ {{\NaHCO}_3}↙{\text "Sodium biocarbonate"} →{ {\CH}_3 {\COONa}}↙{\text "Sodium ethanoate"}+ {{\H}_2 {\O}}↙{\text "Water"}+ {{\CO}_2 ↑}↙{\text "Carbondioxide"}
