Potassium hydroxide solution is produced when potassium reacts with water.
What is the colour of universal indicator when added to potassium hydroxide solution?
Give one reason for your answer.
Colour of universal indicator:
Reason:

When potassium reacts with water, it forms potassium hydroxide (KOH) and hydrogen gas. Potassium hydroxide is a metal hydroxide, which is a type of alkali. Alkalis are substances that produce hydroxide ions (OH⁻) in solution and have a pH value greater than 7. Universal indicator is used to measure pH. In strongly alkaline solutions (like potassium hydroxide, pH 11-14), universal indicator turns blue or purple.
