One solution turns red litmus blue and another turns blue litmus red. What will be the main products on complete neutralisation?
Answer and explanation
Correct answer: Salt and water
The governing concept is acid-base identification followed by neutralisation. A solution that turns red litmus blue is basic, while one that turns blue litmus red is acidic. When suitable amounts react completely, hydrogen ions combine with hydroxide ions to form water, and the remaining ions form a salt. Thus option A is correct; the other choices are not general products of neutralisation.
