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

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

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
