FAQS on indicators used in chemistry
Q: What are indicators used in chemistry?
A: Indicators are substances that change color, fluorescence, or other physical properties in response to chemical conditions like pH or redox potential. Common examples include litmus, phenolphthalein, and methyl orange. They help visualize reactions, especially in titrations.
Q: What are some common types of indicators in chemistry?
A: pH indicators (e.g., phenolphthalein, bromothymol blue), redox indicators (e.g., starch-iodide), and universal indicators are widely used. Litmus is a classic acid-base indicator. Specific indicators are chosen based on the reaction type and required sensitivity.
Q: How are indicators applied in acid-base titrations?
A: Indicators signal the endpoint of a titration by changing color at a specific pH. For example, phenolphthalein turns pink in basic solutions. Selecting an indicator with a pH range matching the titration’s equivalence point ensures accuracy.
Q: Why do indicators change color in chemical reactions?
A: Color changes occur due to structural alterations in the indicator molecule caused by pH shifts or redox reactions. For instance, in acidic conditions, methyl orange turns red, while in basic solutions, it becomes yellow. This reflects protonation or deprotonation.
Q: How do chemical indicators differ from other reagents?
A: Indicators are diagnostic tools that do not participate in the main reaction but provide visual feedback. Reagents, like acids or bases, actively drive chemical changes. Indicators are often used in minimal quantities to avoid interference.
