In a buffer solution consisting of a mixture of weak base and its salt, the ratio of salt to base is increases 10 times, the pOH of the solution will

Options

  1. AIncrease by one units
  2. BDecrease by one units
  3. CIncrease by ten untis
  4. DDecrease by ten untis

Correct answer

A. Increase by one units

Step-by-step solution

pOH = pK a + log salt base If the ratio [ s a l t ] [base ] is increased by 10 folds, then log 10 being 1, the pOH will increase by one unit.
