Question Observe and analyse Figs. 2.13, 2.14, and 2.15, in which red rose extract paper strips are used. Label the nature of solutions present in each of the containers.
The red rose extract turns red in acidic solutions and green in basic solutions. In Fig. 2.13, the red rose extract paper strip turns green, indicating that the solution in this container is basic in nature. In Fig. 2.14, there is no change in the colour of the strip, which shows that the solution is neutral. However, in Fig. 2.15, the strip turns red, indicating that the solution is acidic in nature.
