When diluting a concentrated solution containing an equilibrated mixture of a weak acid and its conjugate base, which statement correctly predicts the pH change?
pH decreases since additional water reduces overall ionic strength, favoring dissociation of the weak acid and lowering the pH.
pH stays the same because the autoprotolysis of water is not significantly impacted by the dilution of low concentrations of weak acid and conjugate base.
No predictable change occurs as unpredictable interactions among various ions weaken predictiveness about the pHydroxide levels.
pH increases due to decreased ratio of acid/base concentration, increasing hydroxide ion concentration and thereby raising the pH.
