Question

How will you prepare 100 ml of N/10 NaHCO3 solution? If 10 mL of this solution is used to
neutralize 12 mL of HCl solution, calculate the normality of this standardized HCl solution.
Standardized HCl solution was used in the volumetric analysis of unknown NaHCO3. In this
analysis, 8 mL of HCl solution was used to neutralize 10 mL of unknown NaHCO3. Calculate the
strength of unknown NaHCO3 solution in gm/L
