Potassium fluotitanate (K₂TiF₆), a starting material forproducing other titanium salts, is made by dissolvingtitanium(IV) oxide in concentrated HF, adding aqueous KF, andthen heating to dryness to drive off excess HF. The impure solidis recrystallized by dissolving in hot water and then cooling to 0°C, which leaves excess KF in solution. For the reaction of 5.00 g of TiO₂, 250. mL of hot water is used to recrystallize theproduct. How many grams of purified K₂TiF₆ are obtained?(Solubility of K₂TiF₆ in water at 0°C is 0.60 g/100)
