Step 1: Understand what titration is. It is a method used to determine the concentration of a solution.
Step 2: Know that during titration, you add one solution to another until a reaction is complete.
Step 3: Realize that mixing is important. If the solutions are not mixed well, the reaction may not happen evenly.
Step 4: Identify the mistake: not swirling the flask while adding the solution.
Step 5: Understand the consequence: if you don't swirl, the solutions may not mix properly, leading to an inaccurate measurement of when the reaction is complete.
