Question

Write the colour changes you observed when you used hibiscus indicator/ turmeric indicator strips in lemon juice and soap solution.​

Answer 1

Explanation:

Tumeric paper is generally used as an indicator to test if solutions are acidic, basic or neutral. Being saturated with turmeric, turmeric papers are yellow in colour. A turmeric paper retains its yellow colour if it is treated with acidic or neutral solutions. It turns bright red if alkaline or basic solutions are added to it. Since a turmeric paper retains its yellow colour when treated with acids, it retains the same colour when lemon juice is added to it as lemon juice is acidic in nature. So the answer for the 1st question is (a) yellow.

Likewise, the answer to the 2nd question is (a) lime water since it does not change the colour of the turmeric paper as it is acidic in nature.
