- A 1.0-L solution that is 4.2 M in ammonia is mixed with 26.7 g of ammonium chloride. a What is the hydroxide-ion concentration of this solution? b 0.075 mol of MgCl2 is added to the above solution. Assume that there is no volume change. After Mg(OH)2 has precipitated, what is the molar concentration of magnesium ion? What percent of the Mg2+ is removed from solution?arrow_forwardWhich salt would you expect to dissolve readily in acidic solution, calcium phosphate, Ca3(PO4)2, or calcium sulfate, CaSO4? Give an explanation.arrow_forwardwhat is concentration of F- ions when 306.960 mg of MgF2 completely dissociate in 1.641 L of water?arrow_forward
