a large amount of potassium in plant food could cause the formation of MgKPO4:6H2O along with MAPH. what would be the effect on the calculated percentage of P2O5 in question 1 if MAPH were mixed in with your precipitate? would the %P2O5 in this mixture be higher or lower than if your precipitate contained only MAPH?
