   30 sty 2023 · A pH less than 7 indicates an acidic solution and a pH greater than 7 indicates a basic solution. Ultimately, the pH value indicates how much H + has dissociated from molecules within a solution. The lower the pH value, the higher concentration of H + ions in the solution and the stronger the acid.
