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 2.670? Express your answer with the appropriate units.
Learning Goal: 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 pH = -log[H30'] H-061 10 pH As pH decreases, acidity increases. As pH increases, acidity decreases. Acidic solution: pH <7 • Neutral solution: pH = 7 Basic solution: pH > 7 Review co Carbonated cola is more acidic than coffee or even orange juice because cola contains phosphoric acid. What...
