Q1:

According to IS : 2720 - 1965, the composition of a dispersing solution used in pipette analysis for determining the size of particles, is

A sodium-hexametaphosphate 33 g, sodium carbonate 7 g and distilled water one litre

B sodium-hexametaphosphate 7 g, sodium carbonate 33 g and distilled water one litre

C sodium-hexametaphosphate 23 g, sodium carbonate 17 g and distilled water one litre

D none of these.

ANS:A - sodium-hexametaphosphate 33 g, sodium carbonate 7 g and distilled water one litre

According to IS : 2720 - 1965, the composition of a dispersing solution used in pipette analysis for determining the size of particles is: sodium-hexametaphosphate 33 g, sodium carbonate 7 g, and distilled water one litre Therefore, the correct option is: sodium-hexametaphosphate 33 g, sodium carbonate 7 g, and distilled water one litre.
