Question

When solid Ni metal is put into an aqueous solution of Pb(NO3)2, solid Pb metal and a solution of Ni(NO3)2 result. Write the net ionic equation for the reaction.

Answer 1

`Pb^(2+)(aq)+Ni(s)\rightarrow Ni^(2+)(aq)+Pb(s)`

Step-by-step explanation:

Hello there!

In this case, according to the given information, it turns out firstly necessary for us to write the complete molecular equation as shown below:

`Pb(NO_3)_2(aq)+Ni(s)\rightarrow Ni(NO_3)_2(aq)+Pb(s)`

Now, we can separate the nitrates in ions as they are aqueous to obtain:

`Pb^(2+)(aq)+2(NO_3)^-(aq)+Ni(s)\rightarrow Ni^(2+)(aq)+2(NO_3)^-(aq)+Pb(s)`

And then, we cancel out the nitrate ions as the spectator ones, for us to obtain the net ionic equation:

`Pb^(2+)(aq)+Ni(s)\rightarrow Ni^(2+)(aq)+Pb(s)`

Best regards!
