extent to which the acid dissociates determines its strength Polar water allows for acids to dissolve Strong Acid - Dissociates completely in a solvent Weak Acid - Releases few hydrogen ions in the solution. ** Lower the pH the stronger the acid**. Strength of Acids.

strong acids almost completely dissociate 10 H2SO4 18 H+ + 9 SO4-2 + 1 H2SO4 10 HCl 9 H+ + 9 Cl- + 1 HCl weak acids only partially dissociate 10 H2CO3 2 H+ + 2 HCO3-2 + 8 H2CO3 18 CH3COOH 3 H+ + 3 CH3COO- + 7 CH3COOH
Often confused Strength (strong or weak) – how acid dissociates Concentration (dilute or concentrated) – amount of acid dissolved in the solution. It is possible to have a dilute solution of a strong acid! Strength and concentration
