P contains hydronium ions.

Solution

Only R

Explanation:

Toluene is a non-polar organic solvent. Hence, HCl dissolves in it but does not ionise to form hydronium ions (H3O+).

Since no hydronium ions are formed, the solution does not show acidic properties and does not react with sodium carbonate to produce carbon dioxide.

Therefore, only statement R is correct.
