Red colour in universal indicator shows which type of solution?
Answer and explanation
Correct answer: Acidic solution
Universal indicator changes colour according to the pH of a solution. Red appears at the low-pH end of the indicator scale, where the concentration of hydrogen ions is relatively high and the solution is acidic. A basic solution generally gives blue to violet shades, while neutral pH gives green. A sugar solution is not identified by this colour alone. Thus, option A is correct.
