2.2 6. (1) Define pH in words. The strong acid HCl has a pH value of 1, use the following equation for a strong acid: HClog → Hag+ Cl And convert the following expression to deduce the hydrogen ion concentration: pH = -log10 [H] (ii) Use the above expression to deduce the pH of HCl (39) given the concentration of the acid to be 4.5 mol/dm³ pH = 2.3
