Turmeric is yellow in colour. When a base is added to it, the solution turns into red colour. However turmeric remains yellow when an acid or neutral solution is added to it. We shall perform the following steps to identify neutral.
1. Take few drops from each solution and test it with turmeric solution. If the solution turn into red colour that solution is lease i.e., Sodium Hydroxide.
2. Now, we will put a drop of sodium hydroxide on a drop of each of the other two liquids seperately, After that we will put the drops of these mixtures on turmeric indicator. The drop which will change the colour of the turmeric indicator to red contains sugar solution. This is because the mixture of basic and neutral solutions is basic in nature.On the other hand, the drop which will not change the colour of turmeric indicator contains hydrochloric acid. This is because hydrochloric acid reacts with sodium hydroxide to from a neutral solution.
