Question
1) Use soilubility rules to determine if the products that will be formed will precipitate (s) or will remain in solution (aq) . Balance the reaction and provide the net ionic equation only if a precioitate is formed .
a- (NH4)2SO4(aq)+Ba(NO3)2(aq)------?
b- NaCl (aq) +AgNO3(aq)-------?
c- Na3PO4(aq) + Mg(NO3)2(aq)-----?
2) a- how many mL of AgNO3 0.150 M solution react with all the cl ion present in a sample of 2,450 g of KCl ? the reaction taking place is
AgNO3 (aq)+ KCl(aq)------Agcl (s) +_ KNO3 (aq)
b-how many grams of Agcl will be produced ?
Explanation / Answer
1)a- (NH4)2SO4(aq)+Ba(NO3)2(aq)-----> BaSO4(S) + NH4NO3(aq)
b- NaCl (aq) +AgNO3(aq)-------> AgCl(s) + NaNO3(aq)
c- Na3PO4(aq) + Mg(NO3)2(aq)----> Mg2PO4(S) + NaNO3(aq)
2) a)No of moles of KCl = 2450/74.55 = 32.86 mole
no of moles of Cl- ions = 32.86 mole
AgNO3 (aq)+ KCl(aq)------Agcl (s) + KNO3 (aq)
1 mole of Kcl = 1mole of AgNO3
M1V1=M2V2
V2 = Volume of AgNO3 required = 32.86*1/0.15 = 219.0 Litre.
b) 1 mole of KCl = 1 mole of AgCl
32.86 mole KcL = 32.86 mole AgCl
mass of agcl produced = 32.86*143.32 = 4709.5 grams = 4.7 Kg
