Answers

Answered by elizabeththomas725

Answer: i cant

Explanation:

because the indicator is colourless so it can change the colour to see if it acidic or alkali but if you add phenolphthalein dye in the indicator, the indicator wont work because the phenolphthalein is pink so therefore wont give a accurate answer to whether it is a acid or alkali.
