write equations for the reactions of NaOH(aq) with solutions containing Al^3+ Cu^2+(aq),Pb^2+(aq) and Fe^3+(aq) ions respectively
This looks straight forward. Do you know the solubility rules?
Al^+3 + 3OH^- ==> Al(OH)3(s)
write equations for the reactions of NaOH(aq) with solutions containing Al^3+ Cu^2+(aq),Pb^2+(aq) and Fe^3+(aq) ions respectively
Sure! Here are the equations for the reactions of NaOH(aq) with solutions containing Al^3+(aq), Cu^2+(aq), Pb^2+(aq), and Fe^3+(aq) ions respectively:
1. Reaction with Al^3+(aq):
NaOH(aq) + Al^3+(aq) → Al(OH)3(s)
2. Reaction with Cu^2+(aq):
NaOH(aq) + Cu^2+(aq) → Cu(OH)2(s)
3. Reaction with Pb^2+(aq):
NaOH(aq) + Pb^2+(aq) → Pb(OH)2(s)
4. Reaction with Fe^3+(aq):
NaOH(aq) + Fe^3+(aq) → Fe(OH)3(s)
Now, let's explain how we arrive at these equations:
When NaOH(aq) (sodium hydroxide) reacts with metal ion solutions, a neutralization reaction occurs, resulting in the formation of metal hydroxides. The general reaction is given by:
NaOH(aq) + MX(aq) → M(OH)x(s) + NaX(aq)
Where M represents the metal cation and X represents the anion from the original salt.
In the case of Al^3+(aq), Cu^2+(aq), Pb^2+(aq), and Fe^3+(aq) ions, the corresponding metal hydroxides, Al(OH)3(s), Cu(OH)2(s), Pb(OH)2(s), and Fe(OH)3(s), are formed respectively.
So, by substituting the metal ions into the general reaction, we obtain the specific equations mentioned above.
I hope this explanation helps you understand how to write the equations for the reactions of NaOH(aq) with different metal ion solutions!
