Common acids
Hydrochloric acid (HCL)
Sulfuric acid (H2SO4)
Nitric acid (HNO3)
Ethanoic acid (CH3COOH)
Common alkalis (soluble bases)
Sodium Hydroxide (NaOH)
Potassium Hydroxide (KOH)
Calcium Hydroxide(Ca(OH)2)
Ammonia (NH3)
Acid - a substance with a PH of less than 7 and forms H+ ions in water
- molecules of hydrogen chloride gas dissolve in water to form hydrochloric acid. In water, these molecules break up or split into ions
HCl --> H+ + Cl-
Difference between a strong and weak acid
- In strong acid solutions, all the molecules are split into ions
- In weak acid solutions, only some of the molecules split into its ions
Alkali - a substance that has a PH of more than 7 and forms an OH- ion in water
- When a sodium hydroxide ion dissolves in water all the ions separate
Difference between alkalis and bases
- A base is a substance that reacts with an acid to form a salt and…
