Question
The decomposition of potassium chlorate (KCIO3)
position of KCIO, Lab ormat Tools Add-ons Help Accessibilit + BIU- Normal text Comfortaa 4. 14 Claim, Evidence, Reasoning for The Decomposition of Potassium Chlorate (KCIO,) Question/Problem: what is the % compositdon of potassium chlorate (KCIO.) in a mixture of potassium chlornate and pocassian chloride (KC)? Discussion/Background: 1. The study of the quantitative relationships oy achencal.ceaction is called stoichiometry 2. When heated, potassium chlorate (KCIO3 decooposes. Oxygen gas is released and potassium chloride (KCI) is formed during the reaction MgO KC10, (s) → KC1 (s) + O2ig) -74.5gmel Percentage of KCI in KC10, =60.82% 122.5 g/mol 3. The decomposition is aided by the presence of a catalyst, manganese dioxide. The MnO, will remain unchanged during the entire reaction process. 4. The potassium chloride (KCI) in the original mixture remains unchanged when heated. Objective: 11 The weight of test tube with cotolyst- W9
