Q: What is the main advantage of using a pH meter over indicators in titrations?
Solution: A pH meter provides a more precise measurement of pH changes during titration compared to visual indicators.
Steps: 5
Step 1: Understand what a pH meter is. It is a device that measures the acidity or alkalinity of a solution in numerical form.
Step 2: Know what indicators are. Indicators are substances that change color to show whether a solution is acidic or basic.
Step 3: Recognize that during a titration, you want to know exactly how the pH of the solution changes.
Step 4: Realize that a pH meter gives you a specific number for pH, which is more accurate than just seeing a color change.
Step 5: Conclude that the main advantage of using a pH meter is its ability to provide precise measurements, making it easier to determine the exact point of neutralization in a titration.
