Question

consider the reaction of 75.0 ml of 0.350 m c₅h₅n (kb = 1.7 x 10⁻⁹) with 100.0 ml of 0.425 m hcl.
what would the total volume of the solution be after the reaction, in ml?

Explanation:

Step1: Add the volumes

When two solutions are mixed, the total volume \( V_{total}\) is the sum of the volumes of the individual solutions.
\(V_{total}=V_1 + V_2\)
where \(V_1 = 75.0\space mL\) (volume of \(C_5H_5N\) solution) and \(V_2=100.0\space mL\) (volume of \(HCl\) solution)

Step2: Calculate the total volume

Substitute the values into the formula:
\(V_{total}=75.0\space mL+ 100.0\space mL\)
\(V_{total}=175.0\space mL\)

Answer:

\(175.0\space mL\)
