General Information:
One liter of this solution contains 36.461 g of hydrochloric acid (HCl).
Procedure:
Measure 95 ml of hydrochloric acid, and add water to make 1,000 ml.
Measure 95 ml of hydrochloric acid, and add water to make 1,000 ml.
Standardization:
Weigh accurately about 1.5 g of sodium carbonate (standard reagent), previously dried at about 270ˆ for 1 hour, dissolve it in 100 ml of water, and titrate with 1 mol/l hydrochloric acid (indicator: 2 drops of bromophenol blue TS). Near the end point, boil to expel carbon dioxide, and immediately continue the titration.
1 ml of 1 mol/l hydrochloric acid = 52.99 mg of Na2CO3
0.5 mol/l Hydrochloric Acid
Prepare and standardize as directed under 1 mol/l Hydrochloric Acid, using
47.5 ml of Hydrochloric Acid.
