HOW MUCH MOLARITY OF STANDARD CONCENTRATED ACIDS (Perchloric Acid 60.0 %w/w) AND FORMULA TO MEASURE THEM
HOW MUCH MOLARITY OF STANDARD CONCENTRATED
ACIDS
(Perchloric Acid 60.0 %w/w) AND FORMULA TO MEASURE THEM
Following
Values are Required of concentrated solutions
:
Molecular
Formula
Molecular
Weight
Assay
or Purity of Acid
Weight
per ml of Acid
Formula:- 1000ml x Wt.per ml x Purity
of Conc. Solution
Molecular
weight x 100
= ? M
Example :- For Perchloric Acid 60.0 %w/w
Following
Values are Required of concentrated solutions
:
Molecular
Formula = HClO4
Molecular
Weight = 100.46
Assay
or Purity of Compound = 60.0%w/w
Weight
per ml of compound = 1.54
Put
the given values in following formula
Formula:- 1000ml x Wt.per ml x Purity
of Conc. Solution
Molecular
weight x 100
= ? M
= 1000ml x 1.54 x 60.0
100.46 x 100
= 9.198 M
Concentrated
Perchloric Acid 60.0 %w/w is about 9.198 M
9.198
M = 1000 ml Conc. Perchloric
Acid 60.0 %w/w
For 1M
= 1000 ml Conc. Perchloric Acid 60.0 %w/w
9.198
= 108.72 ml Perchloric Acid 60.0 %w/w Required
