Potassium Iodide is a metal halide composed of potassium and iodide with thyroid protecting and expectorant properties. To determine the original amount of potassium chlorate in a potassium chlorate-potassium chloride mixture by measuring the oxygen lost from decomposition chemicals used potassium chlorate (KClO3) (1 g) potassium chloride (KCl) (71 g) manganese oxide (MnO2) Jessica Brown Chemistry Lab Write-up December 16, 2008 Decomposition of KClO 3 Purpose: To determine the value of the gas constant, R, by measuring the decomposition of potassium chlorate, KClO 3, using a liquid method. Consider the title reaction, the thermal decomposition of potassium chlorate. Procedure: 1.The mass of the crucible and the cover was measured. 3.The mass of the crucible, cover and KClO3 was measured. Only when that is understood can one start to consider useful applications of the reaction. Experiment 6 – Decomposition of Potassium Chlorate Discussion The percentage composition of a compound is the percent by mass of each element in the compound. In this lab we will observe the products of decomposition of potassium perchlorate (KClO4). Potassium iodide can block absorption of radioactive iodine by the thyroid gland through flooding the thyroid with non-radioactive iodine and preventing intake of radioactive molecules, thereby protecting the thyroid from cancer causing radiation. Correct answers: 3 question: The decomposition of potassium chlorate is used as a source of oxygen in the lab. The Decomposition of Potassium Chlorate Hypothesis: Potassium chlorate decomposes into potassium chloride and oxygen gas, which means that when the glowing splint is inserted into the test tube, the flame will have enough fuel to fully reignite the splint. 1.677mols KCl x (74.548 g / 1 mol KCl) = 125.02 grams KCl so, 125.02g of KCl were formed....and that works out because the decomposition of 205.52g KClO3 would produce 80.49g of O2 To qualitatively demonstrate that the residue resulting from the decomposition of potassium chlorate is … 1 Unit 9 Stoichiometry Notes Stoichiometry is a big word for a process that chemist’s use to calculate amounts in reactions. Upon heating, only the potassium chlorate will decompose. How do you write a balanced equation for this decomposition reaction? Introduction: In this lab we will decompose potassium chlorate (KClO 3) and . Further heating causes it to slowly decompose: 2 KClO Δ ⎯ → ⎯ 2 KCl + 3 O 3 (l) (l) 2 (g) In the presence of manganese(IV) oxide, a catalyst, the decomposition takes place more rapidly: 2 KClO Δ ⎯⎯ → ⎯ 2 KCl + 3 O 3 (l) MnO (l) 2 (g) 2 You will heat the solid mixture of potassium chlorate … When the manganese dioxide is added, this will increase the rate of the production of oxygen in the reaction, … The answer is that reactions are determined by experiment. Potassium chlorate is a compound containing potassium, chlorine and oxygen, with the molecular formula KClO 3.In its pure form, it is a white crystalline substance. Write a balanced equation for the decomposition of potassium chlorate into potassium chloride and oxygen gas. used in this experiment. 1 Normally this reaction requires temperatures of 400°C, but … Consider the title reaction, the thermal decomposition of potassium chlorate. 1. The volume of oxygen collected at 24°C and atmospheric pressure of 762 mmHg is 128 mL. It makes use of the coefficient ratio set up by balanced reaction equations to make connections between the reactants and products in reactions. Using the balanced equation and the fact that all the mass that is lost is oxygen gas, you can use stoichiometry to calculate the mass of potassium chlorate in the original mixture. Examples of the first two types of reaction are 2 Ag2O(s) 4 Ag(s) + O2(g) 2 BaO2(s) 2 BaO(s) + O2(g) Write the balanced equation. upon heating the mixture. We will then predict from our results the correct chemical reaction equation. Two moles of potassium chloride (KCl) and three moles of oxygen (O2) are produced from the decomposition of two moles of potassium chlorate (KClO3). 3. The oxygen gas product will be collected in a 250 mL E. Flask that is … When KClO3is heated strongly, it breaks down releasing oxygen gas and leaving behind a thermally stable (i.e., heat-insensitive) solid residue of an ionic potassium compound. It is the most common chlorate in industrial use. This can be theoretically calculated using atomic masses found on the periodic table, and experimentally calculated from lab data. The potassium chlorate was heated to produce potassium chloride and oxygen. 2.KClO3 was added to the crucible. 1. How many moles of KCIO3 are needed to produce 15 moles of oxygen gas? How many moles of oxygen are produced from 22 moles of potassium chlorate (KClO3) mass of oxygen lost. Careful mass measurements and physical and/or chemical tests allow one to deduce the proper reaction. Using the data from the video, determine the . Chemistry Chemical Reactions Balancing Chemical Equations. Decomposition of Potassium Chlorate . When KClO Potassium chlorate, #KClO_3#, decomposes to form potassium chloride, #KCl# and oxygen gas. The reaction is 2 KClO3 -> 2 KCl + 3 O2. and circle final answers. To experimentally determine the mass percent of oxygen in the compound potassium chlorate (\(\ce{KClO3}\)) via the thermal decomposition of a sample of potassium chlorate.
