How do you make a 1 m mgcl2 solution

Overview:

Magnesium Chloride (MgCl2) is soluble in water. Magnesium chloride is available in anhydrous as well as hydrated forms. Since anhydrous Magnesium chloride is hygroscopic (quickly absorbs water from the air), it is convenient to use hydrated forms that are easy to weigh out the right amount accurately. For this reason, Magnesium chloride hexahydrate (MgCl2.6H2O, Molecular Weight: 203.30) is often used to prepare a 1 M Magnesium chloride solution.

A 1M stock solution can be prepared by dissolving 203.3 g of MgCl2.6H2O (Molecular Weight: 203.30) in water to a final volume of 100 ml.

In the following section, we describe a procedure to prepare 100 ml of 1M MgCl2 stock solution.

REQUIREMENTS

Reagents and solutions
Magnesium chloride (MgCl2.6H2O)
Deionized / Distilled water

Equipment and disposables
Measuring cylinder
Conical flask / Beaker

Composition
1 M Magnesium chloride

Objective
Preparation of 100 ml 1 M Magnesium chloride

PROCEDURE

Step 1: To prepare 100 ml of 1 M Magnesium chloride, weigh out 20.33 g MgCl2.6H2O (Molecular Weight: 203.30) in a 250 ml conical flask/beaker. Add 800 ml deionized/Milli-Q water and mix it.

Tip:
One can use manual shaking using a glass pipette to mix the ingredients. Magnetic stirrer makes the dissolving process easy and convenient.

Precaution:
Do not dissolve in 100 ml of deionized / Milli-Q water. In most cases, solution volume increases when a large amount of solute is dissolved in a solvent.

Step 2: Adjust the volume to 100 ml with deionized / Milli-Q water. Mix it again.

Step 3: Sterilize the solution by autoclaving (20 minutes at 15 lb/sq.in. (psi) from 121-124°C on liquid cycle).

Note:
The solution can also be sterilized by filtering through a filter unit containing a membrane with pore size 0.22 µm or less under sterile conditions.

Storage
The solution can be stored in the cold room.

Follow the table to prepare Magnesium chloride of various concentrations and volumes (10, 100 ml, 500 ml, 1,000 ml, and 10,000 ml).
Solution concentration / Volume	10 ml	100 ml	500 ml	1000 ml	Required amounts of MgCl2.6H2O
0.1 M	0.246 g	2.46 g	30.80 g	24.647 g
0.5 M	1.232 g	12.32 g	61.6175 g	123.235 g
1 M	2.464 g	24.64 g	123.235 g	246.47 g

To prepare 1000 mL of a 0.1 mol/L solution of AlCl3 we have to dissolve 24.1433 g of AlCl3×6H2O (96 % purity) in deionized or distilled water. After the solid is completely dissolved, dilute the solution to a final volume with deionized (distilled) water. we will need to dilute 13.72 mL of 73 % AlCl3×6H2O to a final volume with deionized (distilled) water.

Transfer the prepared solution to a clean, dry storage bottle and label it. Never store solutions in a volumetric flask.

How do you make a 2m MgCl2 solution?

Just before use, add 5 ml of a sterile solution of 2 M MgCl2. (This solution is made by dissolving 19 g of MgCl2 in 90 ml of deionized H2O. Adjust the volume of the solution to 100 ml with deionized H2O and sterilize by autoclaving for 20 minutes at 15 psi [1.05 kg/cm2 ] on liquid cycle.)
