Determination of Hydrochloric Acid Mass Fraction in the Solution

To determine the mass fraction of hydrochloric acid in the solution, we can use the formula:

Mass Fraction (w/w) = (mass of solute / total mass of solution) × 100%

Where: - Mass of solute is the mass of hydrochloric acid - Total mass of solution is the mass of the entire solution

Calculation of Normal Concentration, Molarity, and Titer of the Solution

1. Normal Concentration (N): - Normal concentration is the number of gram equivalents of a solute per liter of solution. - It is calculated using the formula: N = (Molarity × Basicity or Acidity)

2. Molarity (M): - Molarity is the number of moles of solute per liter of solution. - It is calculated using the formula: M = (moles of solute / volume of solution in liters)

3. Titer of the Solution: - Titer is the concentration of a solution as determined by titration. - It is calculated using the formula: Titer = (volume of titrant × molarity of titrant) / volume of sample

Let's proceed with the calculations using the given information.

Calculation Steps

1. Determination of Mass Fraction of Hydrochloric Acid: - We need the specific mass of the hydrochloric acid and the total mass of the solution to calculate the mass fraction.

2. Calculation of Normal Concentration (N): - We need the molarity and the basicity or acidity of the hydrochloric acid to calculate the normal concentration.

3. Calculation of Molarity (M): - We need the moles of hydrochloric acid and the volume of the solution to calculate the molarity.

4. Calculation of Titer: - We need the volume of the titrant, the molarity of the titrant, and the volume of the sample to calculate the titer.

Let's proceed with the calculations based on the provided information.
