Question

When universal indicator is added to the solution of table salt, it turns _________ in colour

Answer 1

The color of salt would turn green at pH 7 when universal indicator is added to the solution.

And since Table salt is NaCl, it becomes neutral in pH with a pH if 7 due to vaguely acidic weak Cl- ions in the solution, hence the table salt solution would exhibit a change to green color of the universal indicator.
