Students perform acid-base titrations to determine the concentration and composition of solutions.
Students standardize solutions using a primary standard.
As enrichment, students may perform a back titration to analyse an antacid tablet or the purity of a solid carbonate. Students produce pH versus volume graphs for a strong acid strong base titration. Data could be collected with a pH probe interfaced with a computer able to plot the titration curve. Students design titration experiments including the appropriate acids or bases, indicators, data table, and calculations. Assess students' graphs of pH titration curves.
