Questions & Step-by-Step Solutions
Which indicator is commonly used in acid-base titrations?
Step 1: Understand what an acid-base titration is. It is a method used to determine the concentration of an acid or a base by reacting it with a base or an acid of known concentration.
Step 2: Learn about indicators. Indicators are substances that change color at a certain pH level, helping to show when the reaction is complete.
Step 3: Identify common indicators used in acid-base titrations. The most common ones are Phenolphthalein, Bromothymol blue, and Methyl orange.
Step 4: Know when to use each indicator. Phenolphthalein is used for strong acid-strong base titrations, Bromothymol blue is used for neutral pH ranges, and Methyl orange is used for strong acid-weak base titrations.
Step 5: Remember that the choice of indicator depends on the pH range of the titration.
