• acids are known as ?

  Proton donors
• bases are known as?

  proton acceptors
• what is an acid?


  a substance that releases H+ ions in water and increases h+ concentration
• what is a alkali?

  a soluble base that produces OH- ions when added to water
• what is a weak acid ?

  and acid with low dissociation that favours reverse reaction
• what is a strong acid?


  An acid that completely dissociates in water to produce hydrogen ions and favours forward reaction
• what is a strong base?


  releases lots of OH- and favours forward reaction
• what is a weak base?

  little OH- released favours reverse reaction
• examples of strong acid?
