PPT-Testing Acid–Base Indicator Colours

002M hydrochloric acid 002M sodium hydroxide Litmus solution Methyl orange Phenolphthalein Tap Water of pH Buffer 7 Insert the sheet into a plastic folder and put the drops on the plastic Place 1 drop of the indicator in each of the circles along the row Now add 1 drop of the reagent shown at the head of the column. Titration. Acid–Base Titration. The concentration of a weak acid or a weak base in water is difficult – if not impossible – to measure directly.. But we can calculate the concentration from the results of titration.. What did one titration tell the other?  . Let's meet at the endpoint.. Why are chemists great for solving problems?   .

This lecture presents the basic concepts of pharmaceutical inorganic chemistry with emphasis on the description, mechanisms and uses of various pharmaceutical products which are clinically used to correct various body disorders. The major topics to be covered are acids and bases, intra and extra cellular electrolytes, the gastrointestinal agents and topical agents frequently employed in the conversion of drugs to chemical forms convenient to their product formulations..
