  1. Reactions of Acid http://www.supergood.ca/blog/2006/05/acid_05.html

  2. Today’s Lesson • Introduction To Acids • Titration Experiment • Complete Questions During Experiment

  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. Today’s Lesson • For today, we will be using CC Lemon (acid) and Sodium Hydroxide (NaOH). The Sodium Hydroxide will be 0.1 mol. • The CC Lemon will have an unknown molar concentration.

  10. Titration Basics • We are using Acid Burettes. This means we always use acids in the burette, and use bases/alkali’s in the conical flask • Always wash the burette and pipette with the liquid you are using, as this cleans them. For today, we will use CC Lemon. • Make sure the tap is closed, and always make sure the glass funnel not fully touching when filling the burette

  11. Things to also know • You will not be marked on today’s work • Today’s work will not be on the test, but is important to know in science • Please wear goggles, as both liquids can hurt your eyes • When getting close to the end of the titration, slow down the amount of liquid coming out of the tap. This will increase your accuracy. • You should complete your questions which completing the experiment today (multi-task – work smarter, not harder!!)

  12. Your Work • Please read Page 46/47 and answer Q 1-6 in sentences.
