1.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?
2. MAPH loses H2O stepwise as it is heated. Between 40 C and 60 C the monohydrate(MAPH) is formed and above 100 C the anhydrous material(MAPH) is formed. What are the Phosphorous % of the monohydrate and anhydrous material?
3.ignition of MAPH( in absence of O2) produces NH3, H2O and magnesium pyrophosphate, Mg2P2O7. Complete and balance the decomposition of MAPH. if 5.00g oh MAPH are ignited, how many grams of Mg2P2O7 would be formed?
