The purpose of the lab is to identify the compound based on a constant composition by performing a serious of tests. The hydrate is solid crystals compound and appears to be dry: since an ionic compound (salt) is crystallized from an aqueous solution (water)‚ by heating the hydrate the water is released from ionic structure; therefore it is possible to measure the weight of the ionic compound and calculate its ratio to the liquid in the hydrate. The goal of the lab is to establish the identity

substances precipitated through qualitative analysis. Solubility rules were also a major theme as solubility is important in determining whether a reaction will produce a precipitate. Starting out the experiment‚ HCl was added to the solution in the test-tube in order to form a reaction between the HCl‚ Ag‚ Pb‚ and Hg cations. The products of this addition of HCl were PbCl2‚ AgCl‚ and Hg2Cl2. After the HCl was added‚ the solution turned a milky white color. It was important to not add too much HCl

Purpose: The purpose of this lab is to give the student a better understanding about projectile motion and to understand Newtons theories and laws of motion. We will be firing the plastic ball from the projectile launcher three times from eight different angles from the ground &

The Charge/Mass (e/m) Ratio of the Electron PHYS 0212: Introduction to Laboratory Physics Fall 2012 Abstract The experiment conducted demonstrated correlation between the charge and mass of an electron and the behavior of magnetic fields. The lab was divided into four parts. The first three parts were conducted with a compass that was used to locate the magnetic field lines around a bar magnet‚ a solenoid and then a pair of Helmholtz coils. As a result of these trials‚ our observations found

China marker‚ I numbered test tubes 1-5 for identification purposes. Using a pipet I added 1 milliliter of each solution to it’s designated test tube. Next‚ I added 5 drops of the Biuret reagent to each test tube and agitated the mixture by shaking the tubes from side to side. After waiting 2 minutes I recorded the color of each mixture. I used the color reaction after adding the reagent to determine the presence of proteins in each substance (Mbuthia‚ 2012). Results Test solutions that contained
