Questions and Answers

What is the formula for calculating the percentage dissociation of an electrolyte?

Percentage dissociation = (alpha * reactant concentration) / (product concentration * 100)

Percentage dissociation = alpha * (reactant concentration / product concentration) * 100

Percentage dissociation = (alpha * 100) * (reactant concentration / product concentration) (correct)

Percentage dissociation = (alpha / reactant concentration) * (product concentration / 100)

What is the relationship between pH and pOH?

pH - pOH = 14

pH = 14 - pOH

pH + pOH = 14 (correct)

pH = pOH + 14

What defines a saturated solution of a sparingly soluble salt?

Molar solubility is the rate at which the salt dissolves in a saturated solution

Molar solubility is the initial concentration of the salt in a saturated solution

Molar solubility is the total concentration of ions in a saturated solution

Molar solubility is the equilibrium concentration of the constituent ions that dissolve to give one liter of saturated solution (correct)

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.
