Neutralization Reaction To play the movies and simulations included, view the presentation in Slide Show Mode. Neutralization Reaction
NEUTRALIZATION Reaction (double replacement RX) an acid and a base react to produce a salt and water
NEUTRALIZATION Reaction (double replacement RX) HBr + KOH KBr + HOH H2SO4 + 2 NH4OH (NH4)2SO4 + 2 H2O 2 NaOH + H2CO3 Na2CO3 + 2 H2O
Acid & Bases Acids are Sour (lemon Juice) Bases are Bitter (milk of magnesia) Acids are Corrosive (BURN skin and insides!). Bases are Caustic (rashes, burning) Each change of 1 on the pH scale indicates 10X more concentration For example: tomatoes compare bananas tomatoes are 10 times more acidic than bananas pH 3 (Grapes) is _____ X more acidic than pH6 (milk) 1000
Liquid Chemicals are another common type of indicator Liquid Chemicals are another common type of indicator. These chemicals change colour at different pH’s. 1 2 3 4 5 6 7 8 9 10 11 12 13 14
There are easy way to tell if something is an Acid or a Base… Acid & Bases There are easy way to tell if something is an Acid or a Base… Acid usually start with Hydrogen (H__) HCl = Hydrochloric Acid H2SO4 = Sulphuric acid H2SO3 = Sulphurous acid Base usually ends with hydroxide (__OH) NaOH = Sodium Hydroxide NH4OH(aq) = Ammonium Hydroxide
Memory trick: heavy metal bands have BASE players! Metal Oxides Example: Strontium Oxide, Lithium Oxide, Copper (II) Oxide Metal oxides react with water to form bases. Na2O(s) + H2O(l) 2NaOH(aq) Memory trick: heavy metal bands have BASE players!
Memory trick: pollution makes ACID RAIN! non-Metal Oxides Examples: carbon monoxide, carbon dioxide, sulphur dioxide Non-metal oxides react with water to form acids SO2(g) + H2O(l) H2SO3(aq) Memory trick: pollution makes ACID RAIN!
Acid Nomenclature Flowchart No Oxygen with Oxygen HCl(aq) = hydrochloric acid HNO2(aq) NO2 Nitrite = nitrous acid HNO3(aq) NO3 - Nitrate nitric acid
