Determine the grams of NaOH that could be absorbed by the SO3/HSO3 buffer before the base absorbing capacity of this buffer were destroyed.
You must supply more of the problem than an overview. How much buffer? What is the pH? But you can work the problem is you know how to use the Henderson-Hasselbalch equation. The buffer capacity is met at pH +/- 1 from the initial pH of the buffer.
