hope it helps u dear

Explanation:

China rose is a natural indicator which changes colour to determine the nature of an acid or a base. Lime juice is highly acidic with a pH of 2.5. A solution of China rose turns green in a basic solution and bright pink or magenta in an acidic solution. Hence, when treated with lime juice it turns into magenta colour.
