• conjugate acid-base = loss or gain of a SINGLE hydrogen ion
• conjugate acid = a base that gains a hydrogen ion
• conjugate base = an acid that donates a hydrogen ion
• PROPERTIES OF ACIDS

  • RED litmus paper
  • usually starts with hydrogen (HCl, H2SO4)
  • reacts with carbonates & bicarbonates
• PROPERTIES OF BASES
