Question

Solid iron is mixed with a solution of copper (I) nitrate to form iron (III) nitrate solution and metal copper. (what is the equation)

Answer 1

Fe + 3CuNO₃ → Fe(NO₃)₃ + 3Cu

Step-by-step explanation:

• Solid Iron = Fe

• Copper (I) nitrate = CuNO₃ (Nitrate, NO₃⁻, always has a charge of -1).

• Iron (III) nitrate = Fe(NO₃)₃ (That way the compound has an overall neutral charge)

• Metal Copper = Cu

Writing the equation using symbols leaves us with:

• Fe + CuNO₃ → Fe(NO₃)₃ + Cu

It is not balanced yet. Now we balance the NO₃ species on the left side:

• Fe + 3CuNO₃ → Fe(NO₃)₃ + Cu

Finally we balance the Cu species on the right side:

• Fe + 3CuNO₃ → Fe(NO₃)₃ + 3Cu
