  1. Metal Acid Reactions http://de-vino.blogspot.jp/2008/04/some-considerations-on-scandals.html

  2. Today’s Lesson • Recap on Acid/Metal Reactions • Complete Experiment • Mole Activity

  3. Reactions of Acids • When you react an acid with an alkali (base), you normally have a very simple reaction that occurs: • Acid + alkali  salt + water • This can be seen with a universal indicator. Hydrochloric Acid will turn red as it’s acidic. • When you add Sodium Hydroxide (alkali), it goes green as it turns neutral. • As more Sodium Hydroxide is added, it will turn blue as there is no more Hydrochloric acid left.

  4. Examples • Sulfuric Acid + Magnesium Hydroxide  Magnesium Sulfate + Water • H2SO4 (aq) + Mg(OH)2 (aq)  MgSO4 (aq)+ 2H2O (l) • Nitric Acid + Potassium Hydroxide  Potassium Nitrate + Water • HNO3 (aq) + KOH (aq)  KNO3 (aq) + H2O (l)

  5. With Metals • With metals, a salt is also produced but there may also be another byproduct such as a gas. • A good example is Magnesium Ribbon in Sulfuric Acid • Magnesium + Sulfuric Acid  Magnesium Sulfate + Hydrogen • Mg (s) + H2SO4 MgSO4 (aq) + H2 (g) • The Magnesium Sulfate can be separated through evaporation.

  6. Carbonates • With Carbonates, acids will normally form 3 substances. These substances are a salt, water and Carbon Dioxide. • An example is Calcium Carbonate + Hydrochloric Acid  Calcium Chloride + Water + Carbon Dioxide • CaCO3 (s) + 2HCl (aq)  CaCl2 (aq) + H2O (l) + CO2 (g)

  7. With Bases • Alkalis are soluble bases. • An example is Copper (II) Oxide + Sulfuric Acid  Copper Sulfate + Water • CuO (s) + H2SO4 (aq)  CuSO4 (aq) + H2O (l) • The salt is Copper Sulfate for this reaction.

  8. Basics • Acid + Metal Hydroxide  Metal Salt + Water • Acid + Metal  Metal Salt + Hydrogen • Acid + Metal Carbonate  Metal Salt + Water + Carbon Dioxide • Acid + Metal Oxide  Metal Salt + Water

  9. Experiment • Please be careful with today’s experiment – it may not seem extremely fun but is slightly dangerous and also important to know. • You must wear goggles!! • Also – please complete the Preliminary Questions before you complete the experiment. • You can find the MSDS sheets by writing MSDS Name of Chemical

  10. The Mole Activity • For today – we are individually going to complete a presentation using PPT/Prezi/Keynote/Mac Whatever to the following questions • Once again – what you are learning here is pivotal to what you will be learning in Grade 9 Chemistry • Try and make it look reasonably presentable

  11. Questions • What is a mole? Give an example of a mole • What is Ar? Explain what it is and give an example • What is Mr? Explain what it is and give an example • How can I work out the number of moles of an element? Give an example

  12. How can I work out the number of moles of a compound? Give an example • How can I work out the mass of a element if I am given the amount in Moles? Give an example • How can I work out the mass of a compound if I am given the amount in Moles? Give an example
