Direct link to this balanced equation:. A chemical equation represents a chemical reaction. It shows the reactants substances that start a reaction and products substances formed by the reaction. However, this equation isn't balanced because the number of atoms for each element is not the same on both sides of the equation. A balanced equation obeys the Law of Conservation of Mass, which states that matter is neither created nor destroyed in a chemical reaction. This is the most straightforward method. It involves looking at the equation and adjusting the coefficients to get the same number of each type of atom on both sides of the equation. Process: Start with the most complex molecule or the one with the most elements, and adjust the coefficients of the reactants and products until the equation is balanced. This method uses algebraic equations to find the correct coefficients. Each molecule's coefficient is represented by a variable like x, y, z , and a series of equations are set up based on the number of each type of atom. Process: Assign variables to each coefficient, write equations for each element, and then solve the system of equations to find the values of the variables.

Potassium compounds are quite common and are extremely useful for a variety of purposes. Potash and other potassium compounds have been used for centuries in the manufacture of glass products. Potassium dichromate is an inorganic chemical compound that possesses immense industrial and laboratory importance. It is an orange crystalline solid with the chemical formula K 2 Cr 2 O 7. It is a strong oxidizing agent and is soluble in water. It is used in the volumetric estimation of ferrous salts , iodides and sulphides for the preparation of chrome alum, chrome yellow and chrome red. K 2 Cr 2 O 7 is an inorganic chemical reagent with chemical name Potassium dichromate. It is also called as Potassium bichromate or Dipotassium bichromate. It is crystalline ionic solid, with a bright red-orange colour.

The oxidizing agent commonly shown is a solution of sodium or potassium dichromate VI acidified with dilute sulfuric acid. If oxidation occurs, the orange solution containing the dichromate VI ions is reduced to a green solution containing chromium III ions. The electron-half-equation for this reaction is. Primary alcohols can be oxidized to either aldehydes or carboxylic acids depending on the reaction conditions. In the case of the formation of carboxylic acids, the alcohol is first oxidized to an aldehyde which is then oxidized further to the acid. You need to use an excess of the oxidizing agent and make sure that the aldehyde formed as the half-way product stays in the mixture. The alcohol is heated under reflux with an excess of the oxidizing agent. When the reaction is complete, the carboxylic acid is distilled off.
