A student took a sodium salt and dissolved it in water. When this aqueous sodium salt solution was tested with universal indicator paper, its pH was found to be 9.
(a) What does pH 9 tell us about the sodium salt solution?
(b) Name one sodium salt which can produce such a solution.

Solution

(a) Sodium salt with universal indicator shows pH = 9 which means that the salt is basic in nature.

(b) Sodium carbonate (Na₂CO₃) can produce such a solution.
