How many grams of anhydrous sodium carbonate can be decomposed using 50mL of seminormal hydrochloric acid?

Answer»

Solution :Number of milli EQUIVALENT of acid `=50xx0.5=25`
Number of milli equivalents of `Na_(2)CO_(3)-25`
Number of milli equivalents of `Na_(2)CO_(3)=25`
1 equivalent =1000m.eq = 53g of `Na_(2)CO_(3)`
25m.eq=?
Weight of `Na_(2)CO_(3)` DECOMPOSED when treated with the given acid solution `=53xx(25)/(1000)=1.325g`
