Potassium nitrate Distilled water Description of the Object of the Experiment Potassium Nitrate: The chemical compound potassium nitrate is a naturally occurring mineral source of nitrogen. It is a nitrate with chemical formula KNO3. Its common names include saltpetre (from Medieval Latin sal petrae: "stone salt" 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

difference between the corrected number of moles and grams of urea and the amount of urea used originally used in the experiment‚ so the ammonium chloride will be primarily compared to the corrected amount of urea to make sure that the amount of solvent is equal. Graph 1 and 5 and Data Table 2 show that the mass of solutes were overall very similar: 8.735 grams of ammonium chloride and 8.99 grams of urea. Overall‚ this experiment proved that the freezing point depression is a colligative property that

There is a lot more than the main food in the package. Usually it has real food then several different chemical compounds and preservatives listed behind the real stuff. In some foods the ingredients include chemical compounds as sodium nitrate and potassium bromate. Sodium nitrite is an ionic compound and is identified by the chemical formula

will be investigating if heating limestone and changing the concentration of the acid will affect the rate of reaction. Preliminary work Before doing our main experiment‚ we will have to conduct another experiment‚ to see what concentration of acid we will have to use. We done this using 0.1M‚ 0.5M and 1M of Hydrochloric acid‚ and 0.1g of powdered limestone‚ we used powdered limestone‚ as it would be a fairer test‚ I think this as all the particles of limestone will be roughly the same size‚ the
