A solution of a strong alkali at concentration 1 M (1 mol/L) has a pH of 14. Thus, in most problems that arise pH values lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible. Weak acid/base
WebbWe use that relationship to determine pH value. pH + pOH = 14 pH + 2.88 = 14 pOH = 11.12 When ammonia solution is diluted by ten times, it's pH value is reduced by 0.5. As an example, 0.1 mol dm -3 ammonia solution is diluted to 0.01 mol dm -3, pH value is reduced from 11.13 to 10.63.
