Question

QUESTION 3 a) A 25 mL of weak base solution is titrated with a strong acid to produce ammonium bromide, NH4Br which is soluble in water. Sketch a well-labelled titration curve and show the equivalence point. b) Calculate the pH of 0.50 M of the salt solution in a). Kb of ammonia, NH3 is 1.8 x10-5. Include all equations associated with the calculation.

Step 1

Step 1: Calculate the pH at the equivalence point using the Henderson-Hasselbalch equation: \[ \text{pH} = \frac{1}{2} \times (14 - \text{pK}_w) - \text{pK}_b - \log[\text{NH}_3] \] Show more…
