Question - Volumetric Analysis and Purity Calculations

A laboratory technician prepares two solutions:
Solution A is 0.100 mol dm^-³ HCl.
Solution B contains 6.0 g of a mixture of anhydrous sodium carbonate (Na₂CO₃) and sodium chloride (NaCl) dissolved in 1.0 dm³ of solution.
A 25.0 cm³ portion of solution B requires, on average, 22.65 cm³ of solution A to reach complete neutralization.

The reaction is as follows:
2HCl + Na₂CO₃ → 2NaCl + CO₂ + H₂O

Calculate the following:

The amount (in mol dm^-³) of Na₂CO₃present in solution B.

The mass of Na₂CO₃ in 250 cm³ of solution B.

The percentage by mass of NaCl (impurity) in the original mixture.

The percentage by mass of pure Na₂CO₃in the original mixture. Get top-notch online assignment help now.
