Question

Two pounds of 44.4 % Potassium Bromate solution at 70°C has been cooled to 10°C. Estimate the amount of crystals to be recovered.

Answer 1

Crystal formation will not occur on the Potassium Bromate at a temperature of $10°C$ . Potassium Bromate has a standard enthalpy of formation $(Δ _f H_{298 })$ of $-342.5 kJ/mol$ . Crystals will only form at a temperature of less than $10°C$
