Here are the observations and inferences for the described experiments, assuming typical results for common inorganic salts.

(a) Dissolve half of sample R in $6\text{ cm}^3$ of distilled water in a test tube. Use portions of this solution as follows:

(i) To $2\text{ cm}^3$ of solution R, add dilute hydrochloric acid. Test any gas evolved with blue and red litmus papers.
