Back (Indirect) Titration - Exam Example Question
Показать описание
I use a writing frame to take you through three separate back titrations, teaching you the 5 basic steps that are generally involved. The first determines the percentage purity of a sample of Magnesium Oxide.The second determines the percenatge of Calcium Carbonate in chalk. The third finds the concentration of Ammonia in a domestic cleaner.
Note that the result of a back titration will be inaccurate if chemical A is contaminated with a chemical that would also react with chemical B.
