PH 75 is the most acid.
pH 9 - pH 4 = pH 5 It is stronger by 5 pH.
Most acidic is substance of pH of 2, then of pH of 5 and the substance of pH 7 is neutral and the substance of pH 11 is basic
The lower the pH, the more acidic the solution is. Remember, pH 7.0 is H2O. As pH decreases below 7, the solution's acidity increases. As pH increase above 7, the basicity of the solution increases. Hence, in the choices you provided, pH 1.0 is most acidic.
pH 0 < acidic < pH 7 neutral = pH 7 pH 7 < basic < pH 14
