The pH of a chemical solution is given by the formula pH log 0 H where H is the concentration hydrogen ions in moles per liter Values of pH range from 0 acidic to 14 alkaline Answer parts a through pH 4 p an integer or a decimal c What is the pH of a solution for which H is 0 00001 pH 5 Type an integer or a decimal d What happens to pH as the hydrogen ion concentration decreases pH increases pH decreases e Determine the hydrogen ion concentration of a solution with pH 3 9 H M Round to six decimal places as needed
