place about 1 mL of tap water on a clean watch glass and gently heat it until water has evaporated. Record if there is any residue and repeat this procedure using deionized water. Next‚ for Water of Hydration section‚ obtain a few crystals of hydrated copper(II) sulfate‚ describe their appearance on the data sheet. Then place the crystals into an evaporating dish‚ place a watch glass over the top of the dish and heat to drive off the water. Move the

Chemistry Lab Report (Redox Reactions) Questions: • What will happen when you put zinc in copper II sulfate? • What will happen when you put copper in copper II sulfate? Predictions: • We can predict that zinc will react with the aqueous solution of copper II sulfate and we will notice a reaction. We can also predict that the copper will not react with the solution of copper II sulfate and no reaction will be noticed. Hypothesis: • It is hypothesized the zinc metal will have a precipitation reaction

the formula of the compound) are expressed in this experiment. In this experiment‚ the goal was to find the formula of copper sulfate pentahydrate by heating a sample of the blue compound in order to evaporate the water and receive the white-colored copper sulfate anhydrous. Using the mass of the original sample of copper sulfate pentahydrate subtracted by the new mass of the copper sulfate anhydrous‚ the mass of water lost is obtained and used to find the empirical formula. The expectation for

Chemical Reactions Lab Synthesis Reactions: Synthesis reactions occur when two elements or compounds combine to create one single compound. The general equation of synthesis reactions is: A+B→AB. The following are the complete balanced equations for the five synthesis reactions performed in the lab. Reaction 1: Reaction 2: Reaction 3: Reaction 4: Reaction 5: The reaction of CO2 and water is a prime example of a synthesis reaction. This is a synthesis reaction because it follows the general
