Sulfuric - Study guides, Class notes & Summaries

A student investigated the rate of the reaction between zinc and sulfuric acid. Hydrogen gas is produced during this reaction. This is the method used. 1. Add 50 cm3 of sulfuric acid to a conical flask. 2. Add 2.0 g of zinc to the conical flask. 3. Quickly put a stopper in the conical flask and start a timer. 4. Measure the time taken to collect 20 cm3 of gas. 5. Repeat steps 1 to 4 three more times. Suggest why the stopper must be put in the conical flask as quickly as possible in step ...

Title: Quantitative and Qualitative Analysis Purpose: The purpose of this experiment is to learn how to measure the amount of a substance that is present in a chemical compound. A metal carbonate will be analyzed to determine how much CO2 and moles of CO2 are lost. Another experiment will also look into how much water a hydrate loses and determine what type of hydrate it is. Paper chromatography will be used to determine the identity of chemical substances. Lastly, SEM/EDX will be used to d...

Title: Organic Synthesis Purpose: In this lab, three carbon based organic compounds were synthesized to determine their true purity. The experiments were done to learn about how to use these compounds’ melting points and infrared spectroscopy to determine their percent yield. Procedure: Experiment 1: Making Acetylsalicylic Acid (aspirin) 1. Obtain a flask. 2. Weigh 2 grams of salicylic acid. 3. Put the 2 grams of salicylic acid into the flask. 4. Put 5 mL of acetic anhydride into a gr...
