How Can The Solubility Of Magnesium Chloride Be Measured Experimentally?

The solubility of magnesium chloride can be measured experimentally by the following steps:

1. Weigh a known amount of magnesium chloride and add it to a certain volume of distilled water, stirring gently until all the salt has dissolved.

2. Keep adding more magnesium chloride to the solution while stirring until no more salt dissolves. This point is known as the saturation point of the solution.

3. Filter the mixture to remove any undissolved solid particles.

4. Measure the volume of the saturated solution obtained.

5. Analyze the concentration of the magnesium ions in the saturated solution using appropriate analytical techniques such as complexometric titration or atomic absorption spectroscopy.

6. Calculate the solubility of magnesium chloride in water at the given temperature by dividing the mass of the dissolved salt by the volume of the saturated solution.

Note: The solubility of magnesium chloride varies with temperature, so it is important to control and record the temperature during the experiment.
