Lab Report

Alex Pascal Lab Partners: November 12, 2009 Period 8 Periodicity in the Properties of Some Representative Elements Purpose: The purpose of this science research lab was to if elements in the same family react similarly. Procedure: A) A rail play subway system, tally subway rack was acquired. A weakened standard of HCl was mensurable in a gradatory cylinder and poured into test tube. accordingly a bunsen burner, a small amount of Mg palm and a woody splint was acquired. The Mg ribbon was whence placed in HCl in the test tube and observed. A small amount of atomic number 20, test tube, and HCl was thusly acquired. The calcium was then offloadped into the test tube with the HCl and observed. B) A test tube, a small amount of piss, and a garden pea size MgO was acquired. The urine and MgO were mixed in concert in the test tube. A drop of Phenolphthaline was dropped into the test tube, and observed. A new test tube, a small amount of water and CaO was acquired. The water and CaO were mixed to make love outher in the test tube. A reaction plate, and small amounts of NaCl, NaBr, and NaI were acquired from the chemical substance station. Each chemical was then poured into a healthy in the reaction plate, and several drops of AgNO3 was added to each.

A large halfway-filled with water beaker was acquired from lab station. Several drops of Phenolphthaline were added to the beaker. A small chunk of Ca was then dropped into the beaker and observed. New material s were acquired, but instead of Calcium, Pot! assium was acquired, dropped in the beaker , and observed. Results: A) No reaction appeared when the Mg ribbon was dropped into the test tube with HCl. Also, no reaction was observed never when a illuminate crack or glowing splint was put inwardly the test tube. B) When the water and MgO were mixed, the water turned very cloudy. Upon adding the drop of Phenolphthaline, the pastiche turned dark pink/purple. When several drops of AgNO3 were...If you indispensability to get a full essay, order it on our website: BestEssayCheap.com
