Answer:
(a) Turmeric Stain turns red because it is washed with soap - a base & turmeric is an indicator and it turns red if it comes in contact with a base.
(b) People who suggested remedy of Lemon Juice are correct. Wasp stings are basic in nature, so adding an acid like Lemon Juice will neutralise the base in the sting.
