PPT-Buffers and Titrations

Dr Harris Ch 21 Suggested HW Ch 21 1 13 29 Buffers Solutions that contain both a weak acid and its conjugate base are called buffers Buffers have the unique ability to resist sharp changes in pH. Antacid tablets contain a material that will neutralize stomach acid about 001 M HCl in normal stomachs but higher after periods of stress and exciting weekends Most brands use calcium carbonate as the active ingredient The tablet could be directly Titration.
