Finding the Ratio of Moles of Reactants in a Chemical Reaction

Finding the Ratio of Moles of Reactants in a Chemical Reaction

I. Purpose
The mark of the testing ground is to be able to find the ratio of jetty reactants in the chemical reaction. The lab uses the method of continuous variations in order to determine the mole ration of two reactants. The chemicals that were utilise in the lab where sodium hypochlorite (NaClO), and sodium thiosulfate (Na2S2O3).
II. Background
In this lab many new concepts where introduced. Such as mole ratios which argon the ratio between the amounts in moles of any two compounds knotty in a chemical reaction. Chemical reaction is the c are for in which one or more substances, reactants, are chemically changed into one or more new substances, products. Reactants are substances that offspring part in and undergo change during a reaction. Products are
substances that is formed as the result of a chemical reaction. some other concept that was introduced with this lab was stoichiometric ratio which is concerned with, involving, or having the exact proportions for a particular chemical reaction. Exothermic was similarly a concept introduced in the lab which is a reaction or process accompanied by the release of heat. And control reagent which is the reactant that is completely consumed when a reaction is run to completion.

Summary of Procedure
In this lab the first procedure was to bankers bill the initial temperature of NaOCl and of Na2S2O3 and measure it with a thermometer and then record it. The same thermometer is used for cadence both solutions, but the thermometer should be washed with distilled water aft(prenominal) the using it in one solution. Afterwards a picayune amount of NaOCl was added to the graduated cylinder. And then add a orotund amount of Na2S2O3 to another graduated cylinder. Then both solutions where poured into a styrofoam cup. Afterward a cardboard with a hole on top was placed on top of the styrofoam cup. And then the thermometer was put in through the hole and used to mix the solutions. Once the...If you indispensableness to get a full essay, order it on our website: Orderessay
