WorksheetsElectrolytes and Degree of Dissociation Quiz
Total questions: 12
Worksheet time: 4mins
What does the Greek letter alpha (α) represent in the context of electrolytes?
The strength of acids
The number of ionized molecules
The degree of dissociation
The total number of molecules
How is the degree of dissociation (α) calculated?
α = N_i - N_tot
α = N_i + N_tot
α = N_tot / N_i
α = N_i / N_tot
What is the formula for expressing the degree of dissociation as a percentage?
α = N_i - N_tot × 100%
α = N_i + N_tot × 100%
α = N_tot / N_i × 100%
α = N_i / N_tot × 100%
