Correct Answer: Titrant wo solution hai jiska concentration pata hota hai.
Step 1: Understand that a titration is a laboratory method used to determine the concentration of a substance in a solution.
Step 2: Identify the two main solutions involved in a titration: the analyte (the solution with unknown concentration) and the titrant (the solution with known concentration).
Step 3: Recognize that the titrant is carefully added to the analyte until a reaction occurs, which is often indicated by a color change or another measurable change.
Step 4: Know that the amount of titrant used helps to calculate the concentration of the analyte based on the reaction between the two solutions.
