What is the weight percent of ki in the original mixture

Reference no: EM13702825

Problem- A 10.0 g mixture of KI and KNO3 is dissolved in 250.0 mL of water. A 20.00 mL portion of this solution is transferred to a volumetric flask and diluted to 100.0 mL with deionized water. A 50.0 mL aliquot of the diluted solution is treated with 2.00 mL of 0.0565 mol/L AgNO3 which precipitates all the I- as AgI. The solution is filtered and treated with KSCN to precipitate the excess silver as AgSCN. 0.0140 g of AgSCN are recovered. What is the weight percent of KI in the original mixture?

Ag+(aq) + I- (aq) à AgI(s)

Ag+(aq) + SCN-(aq) à AgSCN(s)

How many grams of 0.491 wt% HF are required to provide a 50% excess to react with 25.0 mL of 0.0236 mol/L Th4+ by the reaction:

Th4+(aq) + 4 F- (aq) à ThF4 (s)
