PPT-TITRATIONS

What did one titration tell the other  Lets meet at the endpoint Why are chemists great for solving problems   They have all the solutions Titration A lab procedure by which the concentration of acidic or alkaline solutions are examined and determined. 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.
