Process of preparation
In order to prepare a standard solution of oxalic acid, a stock solution of oxalic acid is first prepared. The stock solution is made by dissolving oxalic acid in water. The concentration of the stock solution is then determined. A volumetric flask is then filled with water and the stock solution is poured into the flask. The flask is then swirled to mix the contents. The volume of the stock solution is then recorded. Preparation of Standard Solution of Oxalic Acid – Practical Experiment.
A desired concentration of the standard solution is then selected. The desired concentration is typically 1 or 2 millimoles per liter. A volumetric flask is then filled with water and the stock solution is poured into the flask. The flask is then swirled to mix the contents. The volume of the standard solution is then recorded.
The standard solution is then diluted with water to the desired concentration. A volumetric flask is then filled with water and the standard solution is poured into the flask. The flask is then swirled to mix the contents. The volume of the diluted standard solution is then recorded.
Process of Preparation of Sodium Chloride from Sodium Sulphate
The preparation of sodium chloride from sodium sulphate follows a two step process. In the first step, sodium sulphate is heated to produce sodium sulphide and water. In the second step, the sodium sulphide is reacted with chlorine to produce sodium chloride and sulphur dioxide.
The sodium sulphate is heated to produce sodium sulphide and water. The sodium sulphide is then reacted with chlorine to produce sodium chloride and sulphur dioxide.
Preparation of Acid from the Desired Normality or Molarity from Its Concentrated Solution
The desired normality or molarity can be obtained from its concentrated solution by diluting it with water. The concentration of the acid can be found by multiplying the normality or molarity by the volume of the solution. Preparation of Standard Solution of Oxalic Acid – Practical Experiment.
Finding the Molarity of Oxalic Acid in a 250 ml Solution
The molarity of oxalic acid in a 250 ml solution is 1.0 M.
Equivalent Weight
The equivalent weight is the weight of an element that has the same number of protons as an atom of another element. The equivalent weight is also the weight of an element that has the same number of electrons as an atom of another element.
