HOW MUCH MOLARITY OF STANDARD CONCENTRATED ACIDS (Sulphuric Acid) AND FORMULA TO MEASURE THEM
HOW MUCH MOLARITY OF STANDARD CONCENTRATED
ACIDS (Sulphuric Acid)
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 Conc. Sulphuric Acid
Following
Values are Required of concentrated solutions
:
Molecular
Formula = H2SO4
Molecular
Weight = 98.079
Assay
or Purity of Compound = 98.0%w/w
Weight
per ml of compound = 1.84
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 1.84 x 98.0
98.079 x 100
= 18.38
M
Concentrated
Sulphuric Acid is about 18.38M
18.38M
= 1000 ml Conc.Sulphuric
Acid
For 1M = 1000 ml Conc.Sulphuric
Acid
18.38
= 54.40
ml Conc.Sulphuric Acid Required
