Interpretation:
The value,
and
concentration for given weak acid should be determined.
Concept Introduction:
Weak Acids: Acids that do not easily dissociate into ions completely which has difficulty in proton donation are considered as weak acids. Weak acid forms stronger conjugated base.
: The concentration of hydrogen ion is measured using
scale. The
of a solution is a figure that expresses the acidity or the alkalinity of a given solution.
It is defined as the negative base-10 logarithm of the hydrogen or hydronium ion concentration.
Ionic-product constant for water: It is the hydronium ion concentration times the concentration present in the solution.
