The Solubility Curve of Potassium Nitrate Experiment Report

Purpose: Our purpose here to determine the affects of temperature on yard transits solvability in water. Materials Used in the Experiment: Latex gloves science laboratory coat Safety goggles Thermometer Stir rod try tubes Beaker Weighing dish Hot plate cat valium treat Distilled water Description of the Object of the Experiment Potassium process: The chemical compound potassium nitrate is a variety occurring mineral parentage of normality. It is a nitrate with chemical shape KNO3. Its common land names include flavourpetre (from Medieval Latin sal petrae: stone brininess or possibly Salt of Petra), American English salt peter, Nitrate of potash and nitre. The name salt peter is also applied to sodium nitrate. Description: Potassium nitrate is the oxidizing (oxygen-supplying) agent of black powder. Prior to the large-scale industrial fixation of nitrogen through the Haber process, a major source of Potassium nitrate was the deposits crystallising from cave w alls or the drainings of decomposing organic material. Dung-heaps were a particularly common source: ammonia from the decomposition of urea and other nitrogenous materials would undergo bacterial oxidation to assert nitrate. It was and is also use as a component in some fertilizers. When utilize by itself as a fertilizer, it has an NPK rate of 13-0-44 (indicating 13%, 0%, and 44% of nitrogen, phosphorus, and potassium, by mass, respectively).

Manufacture: Historically, nitre-beds were watchful by mixing spread out with either howitzer or wood ashes, common footing and organic materials such(prenominal) as straw to give porousness to a compost pile! typically 1.5 metres high by 2 metres panoptic by 5 metres long. The heap was unremarkably under a cover from the rain, kept moist with urine, move often to expedite the decomposition and leached with water after rough one year. The liquifiable containing various nitrates was then converted with wood ashes to potassium nitrates, shape and refined for use...
