Hydrochloric Acid VS

Hydrochloric Acid VS HCl = 36.46

For a 0.1m solution Dilute 8.5  ml of hydrochloric acid with sufficient water to produce 1000  ml.

Ascertain its exact concentration in the following manner. Dissolve 0.1  g of anhydrous sodium carbonate in 20  ml of water, add 0.1  ml of methyl orange solution and titrate with the hydrochloric acid until the solution becomes reddish yellow. Boil for 2 minutes and continue the titration until the reddish yellow colour is restored. Each  ml of 0.1m hydrochloric acid VS is equivalent to 5.30  mg of Na₂CO₃.

For a 1m solution Dilute 103.0  g of hydrochloric acid to 1000  ml with water.

Ascertain its exact concentration as described for the 0.1m solution using 1.000  g of anhydrous sodium carbonate dissolved in 50  ml of water. Each  ml of 1m hydrochloric acid VS is equivalent to 53.00  mg of Na₂CO₃.

For a 2m solution Dilute 206.0  g of hydrochloric acid to 1000  ml with water.

For a 3m solution Dilute 309.0  g of hydrochloric acid to 1000  ml with water.

For a 6m solution Dilute 618.0  g of hydrochloric acid to 1000  ml with water.
