Q
Q: What is the purpose of a back titration?
Solution: Back titration is used to determine the concentration of a reactant indirectly by reacting it with an excess of titrant and then titrating the excess.
Steps: 6
Step 1: Understand that back titration is a method used when you cannot directly titrate a reactant.
Step 2: Add an excess amount of a known solution (called the titrant) to the reactant you want to measure.
Step 3: Allow the reaction to complete, so the titrant reacts with the reactant.
Step 4: After the reaction, some of the titrant will be left over because you added more than needed.
Step 5: Titrate the leftover titrant with another solution to find out how much titrant is left.
Step 6: Use the amount of leftover titrant to calculate how much of the original reactant was present.
