Question

write a balanced equation for the reaction of aquenous solutiins of magnesium chloride and potassium phosphate

Answer 1

Overall equation: The equation which shows all of reactants and products in un- dissociated form is called overall equation. For example the overall equation of solutions of potassium bromide and silver nitrate is following: KBr (aq) + AgNO, (aq) → KNO, (aq) + AgBr (s) Complete ionic equation: The equation which shows strong electrolytes as ions is called the complete ionic equation. . For example the complete ionic equation of solutions of potassium bromide and silver nitrate is following K+ (aq) +Br" (aq) + Ag (aq) + NO; (aq) → K+ (aq) +NO; (aq) + AgBr(s) Net ionic equation: The equation which shows only those species in a reaction that undergoes change is called net ionic equation. For example the net ionic equation of solutions of potassium bromide and silver nitrate is following: Br- (aq) + Ag (aq) → AgBr (5) The balanced equation for the reaction of aqueous solutions of magnesium chloride and potassium phosphate molecular: 2K3PO4 (aq) + 3MgCl2 (aq) ---> 6KCl(aq) + Mg3(PO4)2 (s) ionic: 6 K+ (aq) + 2(PO4)-3 (aq) + 3Mg+2 (aq) + 6C1- (aq) ---> 6 K+ (aq) + 6C1-(aq) + Mg3(PO4)2 (8) After cancel out the spectator ions we get net ionic recation as follows: 2(PO4)-3 (aq) + 3Mg+2 (aq) ---> Mg3(PO4)2 (5)
