What is a strong acid?
Completely ionized in aqueous solution.
What is a weak acid?
Only partially ionized in aqueous solution.
What happens to the pH as the concentration of H+ increases?
The pH decreases
What is a concentrated acid and a dilute acid?
Has more moles of acid per unit volume than dilute (dilute refers to solutions of low concentrations).
Are concentrated acids and dilute acids the same as a strong and weak acid?
It’s not the same - concentration is not the same thing as strength of an acid.
Strength refers to whether the acid is completely ionized in water (strong) or only partially (weak).
As the pH is decreases by one unit, what change is seen in the hydrogen ion concentration?
Increases by a factor of 10
