The bag will lose water and the solution in it will become more concentrated. There will be no change. The pH of a solution is 5. Hydrocyanic acid is a weaker acid than acetic acid. Hydrocyanic acid is more soluble in water than acetic acid.
Cyanides are less soluble than acetates.
Acetic acid is a weaker acid than hydrocyanic acid. A 0.20 M solution of the hypothetical weak acid HZ was found to have a pH of exactly 3.0. BaSO 4 to dissolve. Na 2 CO 3 was titrated, the titration curve below was obtained. This suffocating gas dissolves in cold water to produce a mildly acidic solution.
