1.0 M solution of NaOH is mixed with 1.0 M solution of H₂SO₄+ the solution formed is:

Explanation

In the reaction between NaOH and H₂SO₄, sulfuric acid is a diprotic acid, meaning it can donate two protons per molecule. To completely neutralize the acid, you would need two moles of NaOH for every mole of H₂SO₄. In this case, you have equal concentrations of NaOH and H₂SO₄, meaning there is not enough NaOH to fully neutralize the acid, resulting in an acidic solution. The other options are incorrect because the solution cannot be basic or neutral due to the insufficient amount of NaOH for complete neutralization, and the concept of amphoterism does not apply here.
