On igniion, Rochelle salt NaKC_(4) H_(4) O_(6). 4H_(2)O (mol. Wt 282) is converted into NaKCO_(3) (mol wt. 122).0.9546g sample of the rochelle salt on ignition gives NaKCO_(3) which is titrated wih 41.72mL.H_(2)SO_(4). From the follwing data, find the percentage purtiy of the rochelle salt. The solution after neutralisation requires its 1.91 mL of 0.1297N NaOH. The H_(2)SO_(4) used for the neutralisationrequires its 10.27mL aganist 10.35mL of 0.1297N NaOH
