Yes, by definition. If a solution has free hydrogen ions, then it is called an acidic solution.
An acid is commonly defined as any material which, when dissolved in water, results in a solution with an elevated number of hydrogen ions. (Contemporary chemistry uses a slightly different definition of an acid, but the common definition is suitable for this question.)Just a small foot note to this more than adequate answer Hydrogen ions must have moved to a position that has the greatest potential for hydrogen gas But the free electrial pathways needed are not strong enough to over come some framwork which hydrogen must be in to balance negative fields With the free electrial pathways hold more closer to this framwork It gives additional positive Elements greater interaction with negative compounds that are now forming fields for stability
