Final answer:
To write the charge balance for the MgSO₄ and NaNO₃ solution, consider the charges of each ion present and adjust the number of ions to achieve a net charge of zero.
Step-by-step explanation:
In order to write the charge balance for the MgSO₄ and NaNO₃ solution, we need to consider the charges of each ion present.
On the left side of the charge balance, we have H⁺, OH⁻, Mg²⁺, HSO₄⁻, SO₄²⁻, MgHSO₄⁺, MgOH⁺, Na⁺, and NO₃⁻. To balance the charges, we need to ensure that the total positive charge equals the total negative charge.
For example, if we have 1 H⁺ ion with a charge of +1 and 2 OH⁻ ions with a charge of -1 each, then the total positive charge is +1 and the total negative charge is -2, resulting in a net charge of -1. We need to adjust the number of ions present to achieve a net charge of zero, indicating a balanced solution.
