Question

The mass of oxalic acid crystals(h2c2o4.2h2o)required to prepare 50ml of a 0.2n solution is

Answer 1

Answer:

0.63 g is the mass of oxalic acid crystals required to prepare 50 ml of a 0.2 N solution.

Explanation: -

Oxalic acid exists as the dihydrate C₂H₂O₄.2H₂O.

Molecular weight of oxalic acid dihydrate = 126 g / mol.

Gram equivalent weight = Molecular weight / basicity

= = 63 g / mol

1 Normal solution of oxalic acid should have 63 g in 1 L.

0.2 Normal solution of oxalic acid should have

= 12.6 g in 1 L.

0.2 Normal solution of oxalic acid should have in 50 mL.

= 0.63 g in 50 mL.

Answer 2

Explanation:

Solution is Molecular weight of oxalic acid dihydrate = 126 g / mol.

so by the according to the question,

Normal solution of oxalic acid should have 63 g in 1 L. 0.2 Normal solution of oxalic acid should have in 50 mL..
