To calculate the pH of a weak acid, it is important to note that pH has no units, thus it is required to define it with H+ ion concentration.
To calculate the pH of a 0.1 M acetic acid (CH₃COOH) solution with a given dissociation constant (Kₐ = 1.8 × 10⁻⁵), we can follow these steps:Step 1: Write the dissociation equation Acetic acid dissociates in water

Weak Acid: The concentration of the ions formed in the reaction after dissolving a salt of weak acid in the solution can be determined by using the acid dissociation constant value and its appropriate equilibrium constant expression. Answer and Explanation: We are ...
The concentration of free hydrogen atoms is what determines a solution's acidity or alkalinity. This concentration is measured by pH, a term that originally referred to the "power of hydrogen." Household chemicals that are acidic generally have a sour ta
In chemistry, a "buffer" is a solution you add to another solution in order to balance its pH, its relative acidity or its alkalinity. You make a buffer using a "weak" acid or base and its "conjugate" base or acid, respectively. To determine a buffer's pH–or extrapolate from its ...
