Answer 2

China rose is a natural indicator. It acts as follows in acidic and basic medium:

• It turns green in basic solutions.
• This natural indicator turns magenta(dark pink) in acid.
• This indicator can be made easily by soaking some china rose petals in warm for few hours. After few hours a red coloured water is obtained.
• The china rose petals are filtered out. The red coloured water can now be used as a tester/indicator of acid and base.
• Rosa chinensis, also referred to as the China rose, Chinese rose, or Bengal rose, is a species of rose that is indigenous to the provinces of Guizhou, Hubei, and Sichuan in Southwest China.

• So, Y is basic solution and Z is acidic.
