A 250 ml solution is prepared with 1.5 g KCI salt and a 50 ml sample is taken from it. Over 40 ml 0,1100 N AGNO3 is being added. After AgCl is filtered off, it is titrated with KSCN with Fe (III) indicator. Since 5 ml of 0,1N KSCN is spent in the titration, can we find the amount of KCI and the percentage of KCI purity? (K: 39 g/mol, Cl. 35.5 g/mol)
