Multiple choice Solvay process cannot be extnded to manufacture of K2CO3 because of high heat of formation of K2CO3 high solubility of K2CO3 in solution low hydration enthalpy of K+ ion low ionisation enthalpy of K2CO3 Reveal answer Fill a bubble to check yourself B Correct answer Explanation This option is correct because of the high solubility of K2CO3 in solution it cannot be precipitated out as Na2CO3 and hence solvay process cannot be employed for the formation of K2CO3
