Answer 1

a) Calamine lotion can neutralize the acids present in a bee sting and thus give relief from the pain.
b) When factory waste is directly discharged into river then it will lower the pH level of river thus it will cause harm to aquatic life. Therefore factory waste is treated with a base so it doesn't harm the aquatic organisms.
