Violet colour in universal indicator shows which type of solution?
Answer and explanation
Correct answer: Strongly basic solution
The universal indicator colour progresses from red in strongly acidic conditions through green near neutral pH to blue and violet in alkaline conditions. Violet is associated with a high pH, meaning a high hydroxide-ion concentration and strong basic character. Acidic solutions are represented by red or orange shades, and neutral solutions by green. Therefore, option C is the best answer.
