What is the purpose of back titration in the context of acid-base titration?
- To reach the endpoint directly without backtracking.
- To titrate excess acid with a standard base solution.
- To avoid slow reactions in titrating insoluble acids.
- To titrate excess base with a standard acid solution. (correct)
Why is back titration considered an alternative technique to direct titration?
Why is back titration considered an alternative technique to direct titration?
- To account for slow reaction rates in certain titrations. (correct)
- To speed up the determination of equivalence points.
- To achieve more accurate results in acid-base reactions.
- To simplify the titration process in complex reactions.
In back titration, why is excess base added before titrating with a standard acid?
In back titration, why is excess base added before titrating with a standard acid?
- To ensure the reaction goes to completion before reaching equivalence point. (correct)
- To neutralize any remaining acid in the solution.
- To eliminate the need for endpoint indicators.
- To speed up the reaction between the analyte and the titrant.
