Question

ii) In the following change,
Na2SO410H0 let. Na,SO+ 10H2O
Identify.
a) Hydrated substance
b) Anhydrous substance​

Answer 1

Answer:

Molecular mass of Na

2

SO

4

10H

2

O=2×23+32+16×14+1×20=322

On heating the Na

2

SO

4

10H

2

O it becomes anhydrous that means 10 H

2

O molecules separated

Molecular mass of 10H

2

O=20×1+10×16=180

% loss =

322

180

×100=55.9 % =56 %
