carboxylic acids

give the eqn for the partial dissociation of carboxylic acids in water:

state where the PoE lies for the partial dissociation of carboxylic acids in water and explain why:

• PoE lies to the left as most molecules do not dissociate

• ∴ making carboxylic acids weak acids

give the general word eqn for the reaction between an acid and alkali:

acid + alkali → salt + water

give the general word eqn for the reaction between an acid and a carbonate:

acid + carbonate → carbon dioxide + salt + water

give the general word eqn for the reaction between an acid and a metal:

acid + metal → salt + hydrogen

give the eqn for the reaction between ethanoic acid and sodium hydroxide - name the product:

• CH₃COOH + NaOH → CH₃COO^-Na⁺ + H₂O

• CH₃COO^-Na⁺ = sodium ethanoate (this is a salt, not an ester!)

give the eqn for the reaction between ethanoic acid and ammonia - name the product:

• CH₃COOH + NH₃ → CH₃COO^-NH₄⁺

• ammonium ethanoate (this is a salt, not an ester!)

give the eqn for the reaction between ethanoic acid and sodium carbonate and name the product:

• 2CH₃COOH + Na₂CO₃ → CO₂ + H₂O + 2CH₃COO^-Na⁺

• 2CH₃COO^-Na⁺ = sodium ethanoate

give the eqn for the reaction between ethanoic acid and sodium and name the product:

• 2CH₃COOH + 2Na → H₂ + 2CH₃COO^-Na⁺

• 2CH₃COO^-Na⁺ = sodium ethanoate

give the eqn for the reaction between ethanoic acid and magnesium and name the product:

• 2CH₃COOH + Mg → H₂ + (2CH₃COO^-)₂Mg²⁺

• (2CH₃COO^-)₂Mg²⁺ = magnesium ethanoate
