WebbThe value of the pH scale usually ranges from 0 to 14. Also, read: pH of Acids and Bases For an aqueous solution with a temperature of 25°C with pH value, less than 7 is considered as acidic, whereas pH value greater than 7 is considered as alkaline or base. Example: Let us consider the chemical acetic acid having a concentration of 5 Molarity. WebbHence, the pH of the solution is 11.70. (c) 0.002 M HBr. HBr + H 2 O ↔ H 3 O + + Br-[HBr] = [H 3 O +] ⇒ [H 3 O +] = 0.002. ∴ pH = -log [H 3 O +] = -log (0.002) = 2.69. Hence, the pH of the solution is 2.69. (d) 0.002 M KOH. KOH (aq) ↔ K + (aq) + OH-(aq) [OH-] = [KOH] ⇒ [OH-] = 0.002. Now pOH = -log[OH-] = -log (0.002) = 2.69. ∴ pH ...
