Part B 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[H,0" H.0*) - 10 As pH decreases, acidity increases. As pH increases, acidity decreases. • Acidic solution: pH <7 • Neutral solution: pH = 7 • Basic solution: pH > 7 Carbonated cola is more acidic than coffee or even orange juice because cola contains phosphoric acid What is the molar concentration of H.O in a cola that has a pH of 4.2407 Express your answer with the appropriate units.
