1. Chemical Acidity In chemistry, the acidity of a water-based solution is measured by the concentration of hydrogen ions in the solution (in moles per liter). The hydrogen-ion concentration is written [H*]. Because such concentrations usually involve negative powers of ten, negative orders of magnitude are used to compare acidity levels. The measure of acidity used is pH, the opposite of the common log of the hydrogen-ion concentration: pH = -log[H] More acidic solutions have higher hydrogen-ion concentrations. A certain brand of lemon juice has a pH of 2.1, and a certain brand of cleaning ammonia has a pH of 11.6. a) Find the hydrogen-ion concentrations for the lemon juice and the ammonia. b) How many times greater Is the hydrogen-ion concentration of the lemon juice than the ammonia?
