Solubility of kbr
WebKBr(aq) + FeSO4(aq) → FeBr2(s) + K2SO4(aq) KBr(aq) + FeSO4(aq) → no reaction. To determine which reaction will occur, we need to compare the solubility of the two possible products. FeBr2 is insoluble in water, so if it forms, it will precipitate out of solution. K2SO4, on the other hand, is soluble in water, so it will remain in solution. WebThe solubility of KBr at 20°C is 60 g/100 g H 2 O. Increasing the temperature of the solution will likely increase the solubility of KBr. True. False. Expert Answer. Who are the experts? …
