Strengths of Acids and Bases :
Strong acids and bases ionize 100%
Only positive and negative ions remain; no original substance
Weak acids and bases ionize very little (usually <5-10%)
Original substance partially dissociates to form positive and negative ions Strengths of Acids and Bases HCl H2O H+ H+ H+ Cl- Cl- Cl- HF H2O H+ F- HF HF
Is it strong or weak? :
Is it strong or weak? Binary Acids – HCl, HBr, and HI are strong; all others are weak
Ternary Acids (or Oxyacids) – If the difference between # of H and # of O is ≥2, it is a strong acid
Bases – Hydroxides of alkali metals and alkaline earth metals are strong bases
