To determine the volume of sulfuric acid added to the equivalence point, you need to find the point at which the reaction between sulfuric acid and barium hydroxide is complete. At this point, the moles of sulfuric acid added will be equal to the moles of barium hydroxide present in the solution.
First, let's calculate the moles of sulfuric acid added at the equivalence point.
Given:
Sulfuric Acid concentration = 0.020 M
Volume of Sulfuric Acid added = 13 mL
We can use the formula:
moles = concentration (M) × volume (L)
Converting the volume of sulfuric acid to liters:
Volume (L) = 13 mL / 1000 mL/L = 0.013 L
Now, calculating the moles of sulfuric acid added:
moles of sulfuric acid = 0.020 M × 0.013 L = 0.00026 mol
Next, we need to calculate the moles of barium hydroxide at the equivalence point.
Given:
Volume of Barium Hydroxide added = 100 mL
Converting the volume of barium hydroxide to liters:
Volume (L) = 100 mL / 1000 mL/L = 0.1 L
Since the stoichiometry of the reaction between sulfuric acid and barium hydroxide is 1:1, the moles of barium hydroxide will be the same as the moles of sulfuric acid added:
moles of barium hydroxide = 0.00026 mol
Now let's calculate the concentration of barium hydroxide at the equivalence point.
Given:
Volume of barium hydroxide added = 100 mL
Moles of barium hydroxide = 0.00026 mol
The formula to calculate concentration is:
concentration (M) = moles / volume (L)
Converting the volume of barium hydroxide to liters:
Volume (L) = 100 mL / 1000 mL/L = 0.1 L
Calculating the concentration of barium hydroxide:
concentration of barium hydroxide = 0.00026 mol / 0.1 L = 0.0026 M
Therefore, the concentration of barium hydroxide at the equivalence point is 0.0026 M.
