How does molarity affect ph
WebFeb 24, 2024 · Example: If the molarity of an aqueous solution is 6.3 × 10 -5 M, what is the pH? pH = −log [6.3 × 10 -5] = 4.2. You can also calculate concentration from pH and pK a, the latter being derived from the acid dissociation constant Ka. The higher the K a for a particular acid, the stronger the acid it is.
