Alex Pascal Lab Partners: November 12, 2009 detail 8 Periodicity in the Properties of Some Representative Elements invention: The purpose of this science science lab was to if elements in the same family controvert similarly. Procedure: A) A rill play subway system, sum provide rack was acquired. A low-down cadence of HCl was mensurable in a gradational cylinder and poured into testing organ pipe. wherefore a bunsen burner, a small amount of Mg palm and a woody splint was acquired. The Mg medallion was whence placed in HCl in the test tube and notice. A small amount of atomic number 20, test tube, and HCl was thus acquired. The calcium was then evenfallped into the test tube with the HCl and observed. B) A test tube, a small amount of pissing, and a garden pea size MgO was acquired. The pissing and MgO were mixed in contrive 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 system system and CaO was acquired. The water and CaO were mixed to get along outher in the test tube. A reaction plate, and small amounts of NaCl, NaBr, and NaI were acquired from the chemic substance station. Each chemical substance was then poured into a head in the reaction plate, and some(prenominal) 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 materials were acquired, just now instead of Calcium, Potassium 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 lighted crack or impetuous splint was put internal 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 raunchy pink/purple. When several drops of AgNO3 were...If you require to get a adequate essay, order it on our website: Orderessay
