Propanoic acid is a weak carboxylic acid.

The molecular formula of propanoic acid is C3H6O2\text{C}_3\text{H}_6\text{O}_2C3​H6​O2​.

a.

Which ion is released when propanoic acid molecules partially dissociate in aqueous solution to produce an acidic solution?

  • H+\text{H}^+H+
  • OH−\text{OH}^-OH−
  • CO32−\text{CO}_3^{2-}CO32−​

b.

Calculate the relative formula mass (MrM_rMr​) of propanoic acid (C3H6O2\text{C}_3\text{H}_6\text{O}_2C3​H6​O2​).

Relative atomic masses (ArA_rAr​): H=1\text{H} = 1H=1, C=12\text{C} = 12C=12, O=16\text{O} = 16O=16.
