Chlorine Zachary Grindle Chemistry 1301 Professor Bott June 24‚ 2010 Chlorine has an atomic mass of 35.453‚ atomic number 17‚ is a member of the halogen family (VIIA)‚ and its symbol is “Cl”. Chlorine contains 17 protons and 18 neutrons in is nucleus. There are two isotopes for chlorine as well; Cl-35 and Cl-37. Chlorine was discovered in 1774 by Swedish chemist Carl Wilhelm Sheele. Sheele came upon chlorine when he put a few drops of hydrochloric acid (HCl)‚ then known as muriatic acid

heating‚sterilization and combustion. Our instructor‚ Dr. Immel‚ provided us with six heavy metals those metals were: Barium‚ Calcium‚ Lithium‚ Potassium‚ Sodium‚ Strontium. My group got a platinum flame loop‚ and decontaminated it with the water beaker filled half way with water. To light the Bunsen burner my group used a striker‚ which Dr. Immel provided. We started off with Barium‚ when Charlotte put it into the flame it gave the flame a yellow kind of color and a sprinkle of green. After we decontaminated

MOLE RELATIONSHIPS IN A CHEMICAL REACTION PRE-LAB QUESTIONS 1. Balance the equation for the reaction of barium chloride with silver nitrate. 2. Predict the mole ratio of BaCl2 to AgCl for the equation. 3. If an experiment with 10.2 g barium chloride produced 14.5 g silver chloride‚ calculate the experimental mole ratio of silver chloride to barium chloride.

a wooden stick soaked in a metal and nonmetal solution‚ hovered it over a bunsen burner‚ and recorded the color that the flame changed to. The seven solutions we tested were lithium chloride‚ strontium chloride‚ calcium chloride‚ sodium chloride‚ barium chloride‚ copper chloride‚ and potassium chloride. However‚ we had another four additional solutions‚ which had unknown chemical composition. Thus leading us to the guiding question of the lab: what are the identities of the unknown solutions?
