na3po4 (aq) + cr(no3)3 (aq) →
na3po4 (aq) + pb(no3)2 (aq) →
nai (aq) + agno3 (aq) →
nai (aq) + cr(no3)3 (aq) →
nai (aq) + pb(no3)2 (aq) →
na2so4 (aq) + agno3 (aq) →
na2so4 (aq) + cr(no3)3 (aq) →
na2so4 (aq) + pb(no3)2 (aq) →
Step1: Predict products
For \(Na_3PO_4(aq)+AgNO_3(aq)\):
Using the double - displacement reaction rule (\(AB + CD
ightarrow AD+CB\)), the products are \(NaNO_3\) and \(Ag_3PO_4\).
For \(Na_3PO_4(aq)+Cr(NO_3)_3(aq)\):
The products are \(NaNO_3\) and \(CrPO_4\).
For \(Na_3PO_4(aq)+Pb(NO_3)_2(aq)\):
The products are \(NaNO_3\) and \(Pb_3(PO_4)_2\).
For \(NaI(aq)+AgNO_3(aq)\):
The products are \(NaNO_3\) and \(AgI\).
For \(NaI(aq)+Cr(NO_3)_3(aq)\):
The products are \(NaNO_3\) and \(CrI_3\).
For \(NaI(aq)+Pb(NO_3)_2(aq)\):
The products are \(NaNO_3\) and \(PbI_2\).
For \(Na_2SO_4(aq)+AgNO_3(aq)\):
The products are \(NaNO_3\) and \(Ag_2SO_4\).
For \(Na_2SO_4(aq)+Cr(NO_3)_3(aq)\):
The products are \(NaNO_3\) and \(Cr_2(SO_4)_3\).
For \(Na_2SO_4(aq)+Pb(NO_3)_2(aq)\):
The products are \(NaNO_3\) and \(PbSO_4\).
Step2: Check solubility and write balanced equations
- \(Na_3PO_4(aq)+3AgNO_3(aq)
ightarrow 3NaNO_3(aq)+Ag_3PO_4(s)\)
- \(Na_3PO_4(aq)+Cr(NO_3)_3(aq)
ightarrow 3NaNO_3(aq)+CrPO_4(s)\)
- \(3Na_3PO_4(aq)+2Pb(NO_3)_2(aq)
ightarrow 6NaNO_3(aq)+Pb_3(PO_4)_2(s)\)
- \(NaI(aq)+AgNO_3(aq)
ightarrow NaNO_3(aq)+AgI(s)\)
- \(3NaI(aq)+Cr(NO_3)_3(aq)
ightarrow 3NaNO_3(aq)+CrI_3(aq)\) (since \(CrI_3\) is soluble)
- \(2NaI(aq)+Pb(NO_3)_2(aq)
ightarrow 2NaNO_3(aq)+PbI_2(s)\)
- \(Na_2SO_4(aq)+2AgNO_3(aq)
ightarrow 2NaNO_3(aq)+Ag_2SO_4(s)\)
- \(3Na_2SO_4(aq)+2Cr(NO_3)_3(aq)
ightarrow 6NaNO_3(aq)+Cr_2(SO_4)_3(aq)\) (since \(Cr_2(SO_4)_3\) is soluble)
- \(Na_2SO_4(aq)+Pb(NO_3)_2(aq)
ightarrow 2NaNO_3(aq)+PbSO_4(s)\)
