Question

2. Consider the chemical species in the buffer solution before the weak acid has dissociated.
The buffer contains 0.67 M bromous acid. The sodium bromite salt dissociates completely to yield 0.67 M bromite ions and 0.67 M sodium ions.

NaBrO2(aq) ? Na+(aq) + BrO2?(aq)

-What are the chemical species in the buffer before equilibrium is reached?

3. Consider the chemical species in the buffer solution after the strong base has been added and how they will react.
A 0.0018 mol sample of RbOH is added to the buffer solution. Because it is a strong base, it dissociates completely.

-What are the chemical species before a new equilibrium is reached?

.

Explanation / Answer

1) Equation for the net ionic reaction of the strong acid HClO3 with the conjugate base F- is

   HClO3 + F- -------------> HF + ClO3-

2) What are the chemical species in the buffer before equilibrium is reached?

   HBrO2 and NaBrO2

3) Buffer system is not given.
