Retrieved October 14, 2020, from, Save Time On Research and Writing. It is possible to determine the chemical equation for the decomposition of sodium chlorate by applying the principles of stoichiometry to the masses of the reactants and products. Quickly remove the test tube from the flame if a white smoke is given off from the open end of the test tube. Do NOT dispose of exess sodium chlorate in the trash. Distribute the solid evenly along the bottom of the test tube and heat the test tube clamp. Data Table: Trial 1Trial 2Mass of empty test tubeMass of test tube + sodium chlorateColor of burner flame (optional)Mass of test tube + solid product (1st)Mass of test tube + solid product (2nd)Appearance of product Post-Lab Calculations and Analysis: (Show all work on a separate sheet of paper) For each trial, find the initial mass of sodium chlorate and calculate the number of moles of sodium chlorate. All are white solids at room temperature. [12], Sodium chlorate comes in dust, spray and granule formulations. The ultimate products of the thermal decomposition of sodium chlorate are oxygen gas and a white solid.

Based on the molecular formula of sodium chlorate, three possible reactions will account for the loss o f o x y g e n g a s u p o n h e a t i n g ( E q u a t i o n s 1 - 3 ) . Sodium chlorate is the active ingredient in a variety of commercial herbicides. Obtain two medium test tubes. Procedure: Measure all masses to the nearest 0. Allow the test tube to cool completely on a wire gauze with a ceramic, heat-resistant center. § 01 g and record all data in the data table. Some trade names for products containing sodium chlorate include Atlacide, Defol, De-Fol-Ate, Drop-Leaf, Fall, Harvest-Aid, Kusatol, Leafex, and Tumbleaf. 13. Contact with metal powders or combustible organic compounds may cause fires. Sodium chlorate may be used to control a variety of plants including morning glory, canada thistle, johnson grass, bamboo, Ragwort, and St John's wort. The main commercial use for sodium chlorate is for making chlorine dioxide (ClO2). The herbicide is mainly used on non-crop land for spot treatment and for total vegetation control on areas including roadsides, fenceways, and ditches. Reheat test tube #1 gently for an additional three minutes. The solid should begin to melt and bubble slightly. Using a spatula, add approximately 0. Based on the molar masses of the three possible solid products in Equations 1-3, and the number of moles of reactant in each case, calculate the expected masses of the three possible products for Trials 1 and 2. Contact with metal powders or combustible organic compounds may cause fires. &. What the chemical equation for the decomposition of sodium chlorate? It is a white crystalline powder that is readily soluble in water. Holding test tube #1 with the test tube clamp, slowly move the test tube back and forth through the burner flame to gently heat the solid. An ignitor charge is activated by pulling on the emergency mask. 8. When heated above 300 °C, it begins to lose oxygen. In addition, this enzyme is directly denatured by chlorate. It can also kill through root absorption. Á In addition there is a direct toxicity to the proximal renal tubule. If used in combination with 2,4-D, performance is improved.

Sodium chlorate decomposes upon heating or in the presence of metals to give oxygen gas. � N a C l O ( s ) + O 2 ( g ) E q u a t i o n 3 2 N a C l O 3 ( s ) ’! Light a Bunsen burner. Holding the test tube in an almost horizontal position, gently tap the test tube to distribute the solid sodium chlorate evenly along the bottom one-third of the test tube. Based on the molecular formula of sodium chlorate, three possible reactions will account for the loss of oxygen gas upon heating (Equations 1-3). Inspect the test tube for chips and cracks before use and handle the test tube using a test tube clamp. Continue to heat the test tube in the burner flame until no more bubbling is observed and the material in the test tube has solidified. Measure the mass a second time. H I W X ô õ œ Note that equations 1-3 are not balanced.

All of the possible sodium-containing products n Equations 1-2 are real compounds: sodium chlorite, NaClO2; sodium hypochlorite, NaClO; and sodium chloride, NaCl. 14. 12. The purpose of this inquiry-based experiment is to design a small-scale procedure to determine the chemical equation for the thermal decomposition of sodium chlorate.
