(3) The melting point of pure ethanoic acid is 290 K and hence it often freezes during winter in cold climates. Therefore, it is also known as glacial acetic acid. (4) $5-8\%$ solution of ethanoic acid in water (aqueous solution) is called vinegar. (5) Ethanoic acid is a weak acid; but hydrochloric acid is a strong acid as it ionises completely.
