Hard water often contains dissolved Mg2+and Ca2+ions. Water softeners often use sodium carbonate to soften the water. Sodium carbonate is soluble in water, but the carbonate ions form insoluble precipitates with the calcium and magnesium ions, removing them from solution. Suppose a 2.91L solution is 0.0396 M in calcium nitrate and 0.0661 M in magnesium chloride. What mass of sodium carbonate would have to be added to this solution to completely eliminate the hard water ions?
