WebAdditionally, phenol is a weak acid, reacting with sodium hydroxide, unlike aliphatic alcohols. However, it is not acid enough to react with carbonates to produce CO2, unlike carboxylic acids. The absence of these reactions is now explicit in the specification and learners should learn these ‘non reactions’ as well as the reactions of phenol. WebEthanoic acid is a weak acid which means it does not fully dissociate into ions in water. CH 3 COOH ⇌ H + + CH 3 COO - Hydrochloric acid is a strong acid and dissociates fully. HCl → H + + Cl - This means that the concentration of H + ions in 0.4 M HCl is higher than that in 0.4 M ethanoic acid, so its pH is lower and its acid reactions are faster. bar meeting milano
