pH of a Weak Acid - Chemistry Steps

WebIn a mixture of two weak acids, the pH of a mixture will be determined by the stronger acid if its dissociation constant is significantly higher than the weaker acid. For example, in a mixture with an equal concentration of nitrous acid (HNO 2) and hypochlorous acid (HClO), the HNO 2 will be the main determinant of the pH of the mixture as its ... WebIn the case of a weak base versus a strong acid, the pH is not neutral at the equivalence point. The solution is in fact acidic (pH ~ 5.5) at the equivalence point. Let’s rationalize this.
