Which ratio can be used to represent the dissociated water to undissociated water?
$10^{-7} / 55.55$
What distinguishes acidic, neutral, and basic aqueous solutions?
[H3O+] > [OH-]
How is the pH of a solution defined?
Negative logarithm to base 10 of the activity of hydrogen ions
What is the relationship between activity and molarity of hydrogen ions?
Activity can be less or greater than molarity depending on the solution
In a basic aqueous solution, how do [H3O+] and [OH-] concentrations compare?
[H3O+] < [OH-]
Why is measurement of pH essential when dealing with biological and cosmetic applications?
To understand the acidic or basic nature of the solutions

What determines whether a solution is acidic, neutral, or basic?
Hydrogen ion and hydroxide ion concentrations
Why is the pH scale preferred over direct molarity measurements for hydrogen ions?
pH scale provides a convenient logarithmic representation
Explore the concept of saturated solutions and solubility by understanding how sugar crystals form when cooling a thick sugar syrup solution. Learn about the relationship between solute concentration and temperature in a saturated solution, as well as the dynamic equilibrium between solute molecules in both solid and solution states.
