An evaporation-crystallization process of the type described in Example 4.5-2 is used to obtain solid potassium sulfate from an aqueous solution of this salt. The fresh feed to the process contains 19.6 wt% K2SO4. the wet filter cake consists of solid K2SO4 crystals and a 40.0 wt% K2SO4 solution, in a ratio 10 kg crystals/kg solution. the filtrate, also a 40.0% solution, is recycled to join the fresh feed. Of the water fed to the evaporator, 45.0% is evaporated. The evaporator has a maximum capa

SOLVED: Sulfate solution (Na2SO4(aq)) is added to an aqueous solution of potassium bisulfate (KHSO4(aq)). An aqueous sodium hydroxide solution (NaOH(aq)) is also added. Which of the following statements regarding the resultant solution are correct? Select ALL that apply:- The concentration of H3O (aq) increases.- The pH of the resultant solution increases.- The concentration of SO4^2-(aq) increases.- The system shifts toward reactants in order to reestablish equilibrium.- The resultant solution
