\[\ce{Q}\]

1. In the given series of reactions, name the compounds X and Z.
2. Which type of reaction is X to Z?
3. You are given 3 unknown solutions A, B, and C with pH values of 6, 8 and 9.5 respectively. In which solution will the maximum number of hydronium ions be present? Arrange the given samples in the increasing order of H⁺ ion concentration.

Answer 1

1. X = NaHCO₃; Z = Na₂CO₃
2. Decomposition reaction.
3. Solution A.
   Increasing order of H⁺ ions is C < B < A.
