The pH scale was designed to make it convenient to express hydrogen ion concentrations that are small in aqueous solutions. The definiton of pH is in terms of base 10 logarithms. pH = -log[H+] where (H+) is the hydrogen ion concentration. a. If the hydrogen ion concentration in a solution is 4.67 x 10 mol/L, the pH is b. If the pH of a solution is 3.137, the hydrogen ion concentration is mol/L. Taking logarithms and antilogarithms is necessary to...

An acid-base equilibrium system is created by dissolving 0.50 mol CH3CO,H in water to a volume of 1.0 L. What is the effect of adding 0.50 mol CH3CO2 (aq) to this solution? 1. The pH of the solution will equal 7.00 because equal concentrations of a weak acid and its conjugate base are present. Some CH,CO, H(aq) will ionize, increasing the concentration...
