Apparatus: * Pipettes (2) * Tweezers * Spatula (2) * Universal Indicator Paper * Hydrochloric Acid (2M) * Sodium Hydroxide (2M) * Sodium Oxide * Magnesium Oxide * Aluminium Oxide * Silicon Dioxide * Test Tubes (12) * Distilled Water Method: 1. After collecting the required apparatus place the same suitable amount of Sodium Oxide (Na2O) in three different test tubes. 2. In the first test tube add an appropriate amount of distilled water and observe if a reaction occurs. Record these observations. In the solution produced add a small strip of Universal Indicator Paper and record the pH level. 3. In the second test tube add an appropriate amount of Hydrochloric Acid. Observe and record the reaction. 4. In the third test tube add Sodium Hydroxide in an appropriate amount. Observe and record the reaction. 5. Repeat these steps for Magnesium Oxide (MgO), Aluminium Oxide (Al2O3) and Silicon Oxide (SiO2). NOTE: Phosphorus Pentoxide and Sulfur Dioxide were performed by the teacher.
