What color does universal indicator show at pH 5?

Explanation:
Universal indicator uses a blend of dyes that change color as the hydrogen ion concentration changes. As solutions become more acidic (lower pH), the color shifts toward red; as they become more basic (higher pH), it shifts toward blue or purple. At pH 5, the solution is mildly acidic, so the color sits in the orange to yellow range. This is why orange or yellow is the correct color for pH 5. Red would indicate stronger acidity, while blue or purple would indicate basic conditions.
