Take 3.0 mL of concentrated Sulphuric acid (H2so4, sp gr 1.84) into a 1000-ml volumetric flask. Dilute to the mark with water, mix well, and store in a tightly closed glass container.
Standardization of 0.1 N Sulfuric acid with Sodium Carbonate
Take 0.5 oto 1 g of primary standard anhydrouso sdium carbonate (Na2CO3) to a suitable dish or crucible, and dry at 250°C for 4 h. Cool in a desiccator.
Weight accurately 0.22 g of the dried Na2CO3, and transfer to a 250-mL conical flask. Add 50 mL of water, swirl to dissolve the carbonate, and add 2 drops of a 0.1 % solution of methyl red in alcohol. Titrate with the H2so4 solution.
Initial point color End point color
Calculation
Normality of the H2so4 solution(N), as
follows:
N = A /0.053*B
Where
A - gram of Na2CO3 used,
B - used ml of H2so4 solution in titrition.
Ex-
0.2208 gm of Na2CO3
41.6 ml used of H2so4 solution.
Normality of the H2so4= 0.2208/0.053*41.6= 0.1 N
Stability

How much. We’ll need enough to make 2 N, which is 1 M (because there are 2 acidic protons). The molecular weight of H2SO4 is 98 g/mole. Concentrated sulfuric is 98% (usual source) and a density of 1.84 g/mL. For a 1 M solution in 1 L, we’d need 98 g, but, this is for 500 mL so only 49 g of H2SO4 will be required. 49 g / 1.84 g/mL is 26.63 mL.
