Turmeric , Litmus , China rose are natural indicators. All these are prepared from plant extracts or parts.
Turmeric powder can be wetted and spread on paper. That is yellow. When acid is put on it, there is no effect. When a base is put on it, it turns red. So it can indicate only bases.
China rose is a liquid solution. It is rose in color. It becomes pink or magenta when acid is put on it. It becomes green when a base is put on it.
House hold substances:
Tomato juice, Lemon juice, Orange juice, coffee, tea, tap water, butter milk, soft drinks, curries, chutneys etc. The juices are acidic. Soap solutions are basic.
The Turmeric paper could be dipped in substances to note the change in colors. Similarly, a little substance could be dropped inside a cup with China rose solution.
