Answer 1

To calculate the number of moles of NaOH needed to reach the stoichiometric point, you need to perform the following steps: write down the balanced equation, determine the reaction quotient, utilize the ideal gas law, and conduct the titration.

Step-by-step explanation:

To calculate the number of moles of NaOH needed to reach the stoichiometric point, you need to perform the following steps:

1. Write down a balanced equation for the reaction that takes place when the solutions are mixed. For example, the balanced equation for the reaction between NaOH and H₂SO₄ is: NaOH + H₂SO₄ -> Na₂SO₄ + H₂O
2. Determine the reaction quotient (Q), which is the ratio of the concentrations of the reactants and products at any given point during the titration. This can be calculated using the concentrations of NaOH and H₂SO₄ and the stoichiometry of the balanced equation.
3. Utilize the ideal gas law to calculate the number of moles of H₂SO₄ that reacted. The ideal gas law equation is PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.
4. Conduct the titration by adding H₂SO₄ to the NaOH solution until the stoichiometric point is reached. The stoichiometric point is the point at which the number of moles of H₂SO₄ added is equal to the number of moles of NaOH in the solution.
