Question

Direct titration, indirect titration, and back titration simple language define these titration​

Answer 1

Explanation:

Direct Titration:

In a direct titration, an analyte directly reacts with the titrant. The concentration of unknown directly measures from the direct titration.

Indirect titration:

When no suitable detector is available or reactions are slow for direct titration then indirect titration is used to measure the concentration of an unknown solution.  

Back titration:

Back titration is a subcategory of Indirect titration in which an excessive amount of reagent is added to the analyte. After the reaction, the excess amount of reagent is titrated with the titrant. From the remaining amount of reagent and known concentration, an unknown concentration is measured.
