EXPERIMENT 2: Recrystallization and Melting Point Recrystallization (or Crystallization) is a technique used to purify solids. This procedure relies on the fact that solubility increases as temperature increases (you can dissolve more sugar in hot water than in cold water). As a hot‚ saturated solution cools‚ it becomes supersaturated and the solute precipitates (crystallizes) out. In a recrystallization procedure‚ an impure (crude) solid is dissolved in a hot solvent. As this solution is cooled

Chemistry Research Paper What is an anti acid? According to Cindy Quarters (2010)‚ “Antacids are medicines that are taken orally to help relieve sour stomach‚ heartburn‚ or acid indigestion”. This medicine is available without prescription but it is needed to take the correct dose. The different types of anti acids include calcium carbonate‚ sodium bicarbonate‚ magnesium hydroxide‚ aluminum hydroxide‚ and dihydroxyaluminum sodium carbonate. The cost of the anti acid will depend on how effective it is‚

Introduction: Acid rain has proven to be a big problem for Connecticut. It has had a great impact on builders‚ wildlife‚ and the water sources. Acid rain has many components in it such as pollutants from plants to sulfuric acid from burning coal. Problem: Which stone is the most resistant against acid rain? Hypothesis: If we test the different stones against acid rain then red sand stone would be the best because it is heavier and cannot be easily broken. Independent variable: Type of stones

performed and the power developed when climbing a set of stairs and to determine the relationship between power and time. Pre-Lab Questions: 1. Power is the rate at which work is done. The work divided by the time it takes for the work to be done equals power. 2. The unit for power is the Watt which is Joules/second. 3. One horsepower (hp) is 746 watts. Procedure: In this lab‚ we calculated the work performed and the power that person creates when he or she climbs and runs a set of stairs. Each
