Question

Give reason:

a. We need to be careful while diluting acid.

b. Blue colored copper sulphate fades when it is heated.

c. After bee sting we need to apply baking powder.​

Answer 1

Answer:

• Because diluting an acid is a highly exothermic reaction. It may cause the mixture to splash out.....
• Blue coloured copper sulphate (CuSO4. 5H2O) loses water molecules when heated and it becomes colourless.....
• Bee sting is an acidic action and may cause irrition, applying baking soda which is a mild base may neutralises the acid and provides relief.....
