At 25.00 °C, What is the pH of an aqueous 2.50 x 10-8 M HCl solution? The pH of ANY aqueous acid will NEVER be greater than 7.00, REGARDLESS of the acid's concentration! This is because of the "LEVELING EFFECT" of pure water, whose [H+] = 1.0 x 107 M. Thus, the TOTAL [H+] of the solution will be: 1.0 x 107 M +2.50 x 10-8 M = 1.25 x 107 M, thus the pH of the 2.5 x 10-8 M HCl solution will be 6.90 because the contribution of H+ from the autoionization of pure water is greater than that for the very dilute acid, and MUST be accounted for!!!. NOTE: If the acid is di- (or tri-) protic, you must also take that into account!!!

There are different ways to measure pH given in your textbook. From the options listed below, identify the method that would give the least precise reading of pH. A) pH paper B) litmus paper Question 26 of 35 C) pH meter 1. pH paper 2. litmus paper 3. pH meter D) All three options are equally precise. E) Not enough information.

lodic acid (HIO3) is a relatively strong weak acid (K, -0.17). What will be the equilibrium pH of a solution that has an initial concentration of 0.0122 M in iodic acid? (Two decimal places) Type your answer...

In this experiment which is the acid and which is the base: 25.00 ml of 0.500 M HCl neutralized 35.0 ml of NaOH solution.

A weak base solution is 0.33 M base and has pH = 11.90. Determine Kb.

The pH of a chemical solution is given by the formula pH = - log 10 H*], where H is the concentration of hydrogen ions in moles per liter. Values of pH range from 0 (acidic) to 14 (alkaline). Answer parts (a) through (f). (a) What is the pH of a solution for which H* is 0.001? pH = (Type an integer or a decimal.) %3D (b) What is the pH of a solution for which H is 0.0001? pH = (Type an integer or a decimal.) (c) What is the pH of a solution for which H is 0.00001? pH = (Type an integer or a decimal.) (d) What happens to pH as the hydrogen ion concentration decreases? O pH decreases O pH increases (e) Determine the hvdrogen ion concentration of a solution with pH = 3.4.
