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» 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..... |
