Open in App
Solution

  • Loading is the process in which the rate of sedimentation of suspended particles is increased by adding a chemical substance.
  • Sometimes chemical substance is added to the mixture that speeds up the settling of the suspended particles.
  • For example- when alum is added to such a mixture, it dissolves in the liquid, forms lumps with the solid suspended particles, and makes them heavy.
  • So therefore potash alum is the chemical substance that is used for loading.
  • The chemical formula for the potash alum is KAl(SO4)2.12H2O
