Q
Q: What is a back titration?
Solution: A back titration involves adding an excess of a reagent to react with the analyte, then titrating the excess reagent to determine the amount that reacted.
Steps: 6
Step 1: Start with a sample that contains the substance you want to measure (analyte).
Step 2: Add an excess amount of a reagent that will react with the analyte. This means you add more of the reagent than what is needed to completely react with the analyte.
Step 3: Allow the reaction to occur, so the reagent reacts with the analyte.
Step 4: After the reaction, some of the reagent will be left over (excess).
Step 5: Use a titration method to measure how much of the excess reagent is left. This involves adding another solution until the reaction is complete.
Step 6: Calculate how much of the reagent reacted with the analyte by subtracting the amount of excess reagent from the initial amount you added.
