Physical and Chemical Properties Purpose: The Physical and Chemical Properties lab provides the opportunity to investigate the physical and chemical properties of pure chemical substances and analyze the experiment results. Procedure: In the beginning of the experiment‚ I filled two 24-well plates half way with the given chemicals and sucked up these chemicals into their labeled pipets for later use. Following this‚ I performed a number of steps on each of the four test tubes and recorded observations

Experiment 1: Observations of Chemical Changes Purpose: To observe the macroscopic changes that occur in chemical reactions and attempt to interpret the microscopic changes of the atoms and molecules that allow for the macroscopic changes to happen; and to associate these chemical properties with household products. Also‚ it is to learn the importance of how to separate mixtures into their component substances by solubility. Procedure: Before starting with the official experiment‚ it was important

Overview Chemical Warfare is using the chemical properties of a substance to your advantage during war. This has been going on for centuries. Even the most basic forms of weapons were used. People have been putting poison on the end of their spears and arrows since they have been around. Over the years‚ it has also developed into much more advanced chemistry. In this article‚ I am going to focus on the more advanced‚ modern uses of chemical warfare in World War I and World War II. World War

Abstract This experiment is to study the effect of temperature on the rate of reaction between potassium permanganate with oxalic acid. We used 2cm3 of 0.02M potassium permanganate and 4cm3 of 1M sulphuric acid into a test tube. In another test tube‚ we placed 2cm3 of oxalic acid. We placed the test tubes in a water bath at 40‚ 45‚ 50‚ 55 and 60oC respectively. When the solutions have attained these temperatures pour the oxalic acid into the acidified permanganate solution and recorded the time
