What can you predict about the amount of magnesium chloride needed to prepare a solution of MgCl2if the solution can only have a conductivity equal to normal saline? Why?A The amount of magnesium chloride would be greater than the sodium chloride, because the magnesium chloride is less soluble. B The amount of magnesium chloride would be less than the sodium chloride, because magnesium chloride produces more ions. C The amount of magnesium chloride would be greater than sodium chloride, because magnesium chloride produces more ions. D The amount of magnesium chloride would be less than the sodium chloride, because the magnesium chloride is more soluble.
