The fraction of the total moles that dissociate into ions
Study Notes
Electrolyte Dissociation
- The formula for calculating the percentage dissociation of an electrolyte is α = (number of moles of electrolyte dissociated / total number of moles of electrolyte) × 100%.
pH and pOH Relationship
- pH + pOH = 14, indicating an inverse logarithmic relationship between pH and pOH.
Saturated Solution of a Sparingly Soluble Salt
- A saturated solution of a sparingly soluble salt is one that is in equilibrium with undissolved salt, where the rate of dissolution equals the rate of precipitation.
Type of Buffer Solution
- A buffer solution containing a weak acid and its salt with a strong base is called a basic buffer or alkaline buffer.
Degree of Dissociation of an Electrolyte
- The degree of dissociation of an electrolyte represents the proportion of electrolyte molecules that dissociate into ions in a solution.
