Strong Acids
- Strong acids dissociate completely → reaction will go to completion
- [H+] = [HA] → molarity of H+ = molarity of the strong acid
- Strong Acids to know: HCl, HClO4 (Perchloric), HI, HBr, H2SO4 (Sulfuric), HNO3 (nitric)
○ Any other acid is a weak acid and won’t dissociate completely
- [OH-] is going to be small because of equilibrium
- If [HA] < 10⁻⁷ → water is the dominant acid and donates most of the H+ → pH = 7!
○ Only for strong acids!
Strong Bases
- Strong Bases to know: Group 1 hydroxides, Ca(OH)2, Ba(OH)2, Sr(OH)2 → “CaBaSr”
