You <span>preserve the accuracy and precision of your measurements when doing calculations with the measurements by not rounding of the resulting values of the each step in the calculations. It would be recommendable to round off the value only at the final answer. Hope this helps.</span>

As we saw in section 4.3, nitric acid and hydrochloric acid are strong acids. write net ionic equations for the neutralization o
Kazeer [188]

First you write the "molecular" equation, then the ionic equation, and finally the net ionic equation.

Explanation:

You can read about these equations at

Here are the steps for your reaction.

1. Write the molecular equation

We write the equation as if all the reactants were molecules.

2HNO₃(aq) + Mg(OH)₂(s) → 2H₂O(l) + Mg(NO₃)₂(aq

2. Write the ionic equation

We write all the soluble strong electrolytes as ions. H₂O is a weak electrolyte, so we write it as a molecule. Mg(OH)₂ is insoluble, so we write it as a molecule as well.

2H⁺(aq) + 2NO₃⁻(aq) + Mg(OH)₂(s) → 2H₂O(l) + Mg²⁺(aq) + 2NO₃⁻(aq)

3. Write the net ionic equation

Here, we cancel all species that appear on both sides of the equation. We cancel the NO₃⁻ ions.

The net ionic equation is

2H⁺(aq) + Mg(OH)₂(s) → 2H₂O(l) + Mg²⁺(aq)
