Answer: 14.62 ml
Explanation:
Molarity is defined as the number of moles of solute dissolved per liter of the solution.
where,
n= moles of solute
= volume of solution in ml = 250 ml
Now put all the given values in the formula of molarity, we get
To calculate the volume of base, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is NaOH.
We are given:
Putting values in above equation, we get:
Thus the volume of NaOH solution the student will need to add to reach the final equivalence point is 14.62 ml

The <u>correct net ionic equation</u> for the chemical equation involving the reactants Ba(OH)2(aq) and H2SO4(aq) is Ba²⁺ (aq) + 2OH⁻ (aq) + 2H⁺(aq) + SO4²⁻ (aq) --> BaSO₄(s) + H₂O(l)
<h3>Further Explanation
</h3>
The chemical reaction between Ba(OH)2(aq) and H2SO4(aq) will be given by;
Ba(OH)₂(aq) + H₂SO4(aq) --> BaSO₄(aq) + 2H₂O(l)
<h3>Net ionic equations </h3>
- Net ionic equations that do not include all ions that are present in the reactants and products.
- The equations only includes the ions that are involved in the reaction.
- The ions that are not involved in a chemical reaction are called spectator ions and are cancelled out while writing ionic equations.
- Reaction between Ba(OH)2(aq) and H2SO4(aq is an example of a neutralization reaction or a double displacement reaction.
- During the reaction Barium ion bonds with sulfate ions and forms barium sulfate which is a solid, while hydrogen ion bonds with hydroxide ion to form water which is a liquid
That is:
Ba(OH)₂(aq) + H₂SO4(aq) --> BaSO₄(s) + 2H₂O(l)
- Barium ion changes from aqueous to solid state barium sulfate there it is an ion involved in the reaction.
- Additionally, all the other ions are also involved in the reaction since they have changed their initial state. The chemical reaction has no spectator ions.
Therefore; the ionic equation required will be;
Ba²⁺ (aq) + 2OH⁻ (aq) + 2H⁺(aq) + SO4²⁻ (aq) --> BaSO₄(s) + H₂O(l)
