Explanation:
This activity uses turmeric, a common spice in curry, as an indicator for acidity and basicity. Turmeric is yellow in acid and neutral substances, but turns bright red with bases. Learners can use their indicator to test household chemicals and determine which are basic.Because it is solubilized. At neutral or acidic pH is not soluble. Alkaline conditions cause the deprotonation of some of the functional groups making the molecule "more polar". It makes sense giving for three acidic protons.
