Practice Questions on Acid Base Titration
1. What will be the pH at the equivalence point of the reaction when 50 mL of 0.257 M HBr is titrated with 0.450 M KOH solution? (Answer: pH = 7)
2. What is the trend of pH change in the titration between a weak acid and a weak base.
3. Why do the salts of weak acid and weak base hydrolyze in the solution?
4. In the titration of strong acid vs strong base, what trend of pH is observed?
5. How is an indicator selected for detecting the pH change in acid-base titrations?
Acid Base Titration
Acid Base titration is a fundamental method in the quantitative chemical analysis used to determine the concentration of acids or bases in a solution. This process involves the controlled addition of a known concentration of an acid or base (titrant) to a solution of the substance being analyzed until the reaction reaches a neutral point. The moles of acid and base are equal at this equivalence point, resulting in a neutral solution. A pH indicator is often used to monitor the progress of the reaction, and a titration curve can be constructed to visualize the pH changes throughout the titration process.
In this article, we look into what is acid-base titration, titration curve, choice indicator, etc.
