- I Review | Constants | Periodic Table Learning Goal: Part A To calculate pH and use it as a measure of acidity. The pH expresses the molar concentration of hydronium ions in an aqueous solution on a logarithmic scale: What is the pH of an aqueous solution with [H30+] =2x10-14 M? Express the pH numerically using one decimal place. pH = -log[H3O+] • View Available Hint(s) [H3O+] = 10-pH As pH decreases, acidity increases. As pH increases, acidity decreases. • Acidic solution: pH 7 pH = Submit Part B Carbonated cola is more acidic than coffee or even orange juice because cola contains phosphoric acid. What is the molar concentration of H3O+ in a cola that has a pH of 3.120? Express your answer with the appropriate units. • View Available Hint(s) [H3O*] = Value Units Submitarrow_forwardDetermine the pH of a solution with [H3o*] = 1.73 x 10-5 M.
