Question

List the materials and chemicals required for
getting barium sulphate​

Answer 1

Explanation:

Aim: To obtain Barium Sulphate.

Chemicals required: Barium Hydroxide, dil. Sulphuric Acid.

Overall reaction:  $Ba(OH)_{2}$ + $H_{2} SO_{4}$ ⇒ $BaSO_{4}$ + $H_{2}O$

Note: There are other alternative chemical reactions to get to Barium Sulphate but, I find this reaction to be the safest. The other reactions include toxic gases like $H_{2}S$ and strong acids such as $HNO_{3}$ and $HCl$ which should be handled with care.
