What is the effect of increasing the concentration of a reactant in a titration?
Correct Answer: Increasing the concentration of a reactant will require a greater volume of titrant to reach the equivalence point.
Step 1: Understand what a titration is. It is a method used to determine the concentration of a solution by adding a reactant of known concentration.
Step 2: Identify the reactant whose concentration is being increased. This is the substance you are measuring.
Step 3: Recognize that increasing the concentration means there are more molecules of the reactant in the same volume.
Step 4: Realize that to neutralize or react with these additional molecules, you will need to add more of the titrant (the solution of known concentration).
Step 5: Conclude that as the concentration of the reactant increases, the volume of titrant needed to reach the equivalence point (where the reaction is complete) also increases.
