Title	Zinc and sulfuric acid reaction
Caption	The drawing shows a laboratory apparatus for the reaction of zinc with sulfuric acid to produce hydrogen gas. The hydrogen can be collected by displacement of water from a test tube inverted in a pan of water.
Keywords	zinc, sulfuric acid, hydrogen gas, activity series, cation, anion, salt

Title	Three acid-base reaction theories
Caption	The Arrhenius model of acids and bases was broadened in scope by the Brqnsted-Lowry model. The Lewis acid-base model is the most general in scope. The Lewis definition of an acid includes any substance that is an electron pair acceptor; a Lewis base is any substance that can act as an electron pair donor.
Keywords	acid, base, theory, Arrhenius, Brqnsted-Lowry, Lewis, model

Title	pH scale
Caption	The pH scale shows the classifications used for acidic, neutral , and basic solutions.
Keywords	pH, scale, acid, base, neutral, solution, log, hydrogen ion, concentration

16-10ab

Title	Effect of acids and bases on ph and pOH
Caption	The graphs show the effect of adding excess acid or excess base on the pH and pOH of a solution. (a) When excess acid is added, pH decreases, and pOH increases. (b) When excess base is added, pH increases, and pOH decreases.
Keywords	excess, acid, base, pH, pOH, solution

16-13

Title	Laboratory apparatus for titration
Caption	An apparatus for titration. A sample of unknown acid is measured into the flask, and an acid-base indicator is added. Base from a buret is added dropwise until the indicator changes color.
Keywords	apparatus, titration, buret, standard base, end point, concentration, acid-base, indicator
