General Chemistry- Single replacement Lab Name: ___________ Date: ____________ Objective: To observe chemical reactions that belong to the category of single replacement reactions. To write and balance equations that show the reactions. To separate products from solutions when necessary. Materials: Hand lens copper tinsel (2 pieces) test tube rack Solutions: .1M silver nitrate watch glass magnesium (12 pieces) 10ml graduated cylinder 1M hydrochloric acid 3 test tubes 1M sulfuric acid 1M acetic acid Procedures: Silver Nitrate – Copper Lab 1. 2. 3. 4. Obtain a hand lens and a clean watch glass (wash it if necessary) Put a small rolled piece of copper tinsel on the watch glass. Put a drop or two of silver nitrate on the copper wire. List your observations. a) Observations of copper wire and silver nitrate before the experiment. b) Observatons of copper wire and silver nitrate after the experiment. What changes Occurred? Write the word equation and balanced chemical equation if you observed a reaction. (word)________________________________________________________________________ (balanced)_____________________________________________________________________ _ Procedures: Acid Lab 1. Obtain 12 pieces of Magnesium 2. Put 4 pieces of magnesium in 3 separate test tubes. 3. Add 2ml of hydrochloric acid to the first test tube, 2ml of sulfuric acid to the second test tube and 2ml of acetic acid to the third test tube. Make sure you rinse the graduated cylinder out EACH TIME you use it!! 4. Record observations below and indicate which acid reacts fastest, which not at all. Magnesium + Hydrochloric acid Magnesium + sulfuric acid Magnesium + acetic acid 5. What is the usual indication of a chemical reaction involving acids and metals? 6. Write a word equation with symbols and a balanced chemical equation for every reaction. 1a. ______________________________________________________________________________ 1b. ______________________________________________________________________________ 2a. _______________________________________________________________________________ 2b. ________________________________________________________________________________ 3a. ________________________________________________________________________________ 3b. ________________________________________________________________________________
