Important points on acidic and basic substances:

• The taste of acid is sour. On the other hand, the taste of basic substances is bitter.

• We can use two indicators, that are- litmus paper and phenolphthalein to check the acidity of a substance. If the blue color of litmus paper turns red, then it it is confirmed that the substance is acid. And if phenolphthalein changes to colourless, it indicates acidity of a substance.

• Whereas the red litmus paper will change into a blue one, if it is dipped in a substance or liquid which is basic.

• When we react both base and acid together, the product that are formed will be water and base.
