What is the pH of a 0.00138 M hypochlorous acid (HClO) solution?  Ka = 3.5 * 10-8 Report your answer to two decimal places.

Determine the concentration of a NHCl aqueous solution that has a pH = 5.975.  The base ionization constant of ammonia, NH, is: Kb=1.78 × 10-5.  Round off your answer to 3 sig. figs.  Reaction: NH4Cl (aq) → NH4+ (aq) + Cl- (aq)               NH4+ (aq) + H2O (l) ↔ NH3 (g) + H3O+ (aq).

pH is a logarithmic scale used to indicate the hydrogen lon concentration, [H], of a solution: pH = -log[H] Due to the autoionization of water, in any aqueous solution the hydrogen lon concentration and the hydroxide ion concentration, (OH], are related to each other by the K of water K.-HOH -1.00 x 10-¹4 where 1.00 x 104 is the value at approximately 297 K Based on this relation, the pH and pOH are also related to each other as 14.00 pH + POH The temperature for each solution is camned out at approximately 297 K Part A ▸ 0.55 g of hydrogen chloride (HCT) is dissolved in water to make 55L of solution.
