Acid Base Concepts

Name a common Arrhenius base.

• Ammonium sulfate ((NH4)2SO4)

• Sodium hydroxide (NaOH)

• Potassium chloride (KCl)

According to Arrhenius theory, an acid is a substance that:

• Increases the hydroxide ion concentration in solution
  

• Increases the hydrogen ion concentration in solution

• Accepts a proton from another substance
  

• Donates an electron pair in solution
