Calculate the percentage of anhydrous sodium carbonate in the sample if a solution containing 2.5 g sodium carbonate sample is neutralized completely by 55 cc of N/2 HCL.
Solution: Given, Weight of Sodium Carbonate= 2.5gm Volume of HCL(V) = 55ml Normality of HCL (N) = $\frac{1}{2}$N=0.5N So, Purity Percentage = $\frac{…
