Strong vs weak Acids and Bases

Strong acids

  • HCl

  • HBr

  • HI

  • HNO3

  • HClO4

  • H2SO4

Strong Bases

  • LiOH

  • NaOH

  • KOH

  • RbOH

  • CsOH

  • Ca(OH)2

  • Sr(OH)2

  • Ba(OH)2

Weak Acids

  • HF

  • Acids in which H is not bonded to O or to a halogen (HCN

    and H2S

  • Oxoacids in which the number of O atoms equals or exceeds

    by one the number of ionizable protons, such as HClO,

    HNO2, and H3PO4

  • Organic carboxylic acids (general formula RCOOH) such as

    CH3COOH
