Yuno wants to assess the quality of water in the Clover Kingdom and the Heart Kingdom. In order to do this, he took a 200.0 ml sample (T= 20oC) from the two areas and titrated them with sodium thiosulfate. The water from the Clover Kingdom used up 7.15 ml of the titrant while 7.65 ml where used on the Heart Kingdom’s water. Prior to this, 0.1000g of potassium iodate (FM: 214.01 g/mol; 99.97% purity) was weighed and subsequently dissolved in 150.0 ml of distilled water. He took 20.00 ml aliquot of this solution and added
