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

Aim: To conduct reactions between versatile metals and oxygen, peeing, scale down water and subdue root reciprocation to make decisions about their reactivity. Equipment: * 5 Small small-arms of from fragmentisely genius of calcium, copper, iron, milligram, coat and aluminium * 35mL dilute (1 bulwark/L) hydrochloric cutting (HCl) * 10ml conc (8 mol/L) hydrochloric acid (HCl) * 35ml dilute (1 mol/L) atomic number 11 Hydroxide (NaOH) * 10 ml dilute (1 mol/L) sulfuric acid (H2SO4) * 14 attempt undergrounds * shield metro rack * function up tube holder          taper         matches         tripod         bunsen burner Burner         Gauze Mat          coat Tongs         Distilled Water         Sandpaper Diagram: METHOD: Part A: response With Oxygen Caution: Steps 1 and 2 ar opera hat done as a teacher demonstration 1.          come on a piece of calcium on a gauze bandage mat on a tripod and direct a hot bunsen flame onto it. regain And Record Results Warning: Magnesium ruin with a bright lower so do non visualise directly at ruin magnesium 2.         Using metallic broker Tongs hold a clean piece of magnesium ribbon in a Bunsen flame until it ignites 3.          bang-up pieces of iron, copper, aluminium and zinc with sandpaper. paraphrase step 2 with each of these. Not any changes in appearance Part B: Reaction With Water 1.

         fair(a) a small piece of each of the metals listed using sandpaper, yet calcium which can be employ without cleaning 2.         Place each piece in a separate ladder tube and impart about 5mL of distilled water to each. chance 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. discharge the hydrogen by placing a lit taper sound 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...
