Chapter 17, Problem 20QP
Interpretation Introduction
Interpretation:
A weak acid from the given acids is to be selected to prepare a buffer solution at
Concept Introduction:
A buffer solution is a chemical solution that resists changes in its pH value even when small amounts of the acid or the base are added to it. It is a mixture of a weak acid with its salt of the strong base or a weak base with its salt of the strong acid.
A weak acid is an acid that does not dissociate completely into water.
