Experiment Prac Writeup. for reactions between metals and oxygen, water, dilute water and dilute alkali.

Aim: To conduct reactions between various metals and oxygen,water, scale polish water and subdue root word to make decisions most their reactivity. Equipment: * 5 Small pieces of from steally one of atomic number 20, copper, iron, magnesium, coat and atomic number 13 * 35mL slue (1 mol/L) hydrochloric acid (HCl) * 10ml conc (8 mol/L) hydrochloric acid (HCl) * 35ml slue (1 mol/L) Sodium Hydroxide (NaOH) * 10 ml dilute (1 mol/L) sulfuric acid (H2SO4) * 14 hear undergrounds * bulwark tube rack * turn up tube pallbearer          taper         matches         tripod         Bunsen Burner         Gauze Mat          coat pair of tongs         Distilled Water         Sandpaper Diagram: METHOD: Part A: reaction With Oxygen Caution: Steps 1 and 2 ar best done as a teacher demonstration 1.          come on a piece of calci um on a gauze mat on a tripod and direct a calefacient bunsen flame onto it. mention And Record Results Warning: Magnesium destroy with a shiny light so do non look directly at burning magnesium 2.         Using metallic element pair of tongs hold a clean piece of magnesium ornament in a Bunsen flame until it ignites 3.          peachy pieces of iron, copper, atomic number 13 and zinc with sandpaper. Repeat step 2 with each of these. non any changes in appearance Part B: Reaction With Water 1.

         fair(a) a small piece of each of the metals listed apply sandpaper, yet calcium which can be used without killing 2.          Place each piece in a separate test tube a! nd add about 5mL of distilled water to each. commemorate and record any change. 3.         If Reaction occurs collect the gas by inverting another test tube over the one in which the reaction I occurring. Test the hydrogen by placing a lit taper near the mouth of the test tube. A pop shows hydrogen is present. 4.         If, by and by a couple of minutes, no reaction occurs heat the test tube in a quiet Bunsen...
