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.
