Sodium tripolyphosphate (Na,P,O1) is used in many syn- thetic detergents. Its major effect is to soften the water by complexing Mg+ and Ca* ions. It also increases the effi- ciency of surfactants, or wetting agents that lower a liquid's surface tension. The K value for the formation of MgP,O is 4.0 x 10'. The reaction is Mg* (aq) + P,O, (aq) - MgP,O, (aq). Calculate the concentration of Mg* in a solution that was originally 50. ppm Mg* (50. mg/L. of solution) after 40. g Na,P,O10 is added to 1.0L of the solution.
