An industrial chemist is analyzing a liquid waste stream, Solution Q, which is suspected to contain a dilute mineral acid. The liquid has already been shown to conduct electricity.
Devise an experiment, other than measuring conductivity or using indicators, to demonstrate another characteristic chemical property of acids using a sample of Solution Q. Describe the reagent used and the expected observation.
