What Is The Solubility Of Aluminium Bromide In Different Solvents?

Aluminium bromide (AlBr3) is a compound that can dissolve in various solvents to varying degrees. The solubility of AlBr3 depends on several factors such as the polarity and structure of the solvent, temperature, pressure, and the presence of other solutes.

In polar solvents like water and ethanol, AlBr3 dissolves readily due to the ionic nature of the compound. When AlBr3 dissolves in water, it undergoes hydrolysis to form hydrobromic acid and aluminium hydroxide. The solubility of AlBr3 in water at room temperature (25°C) is approximately 68 g/100 mL. However, the solubility decreases with increasing temperature due to the endothermic nature of the dissolution process.

In nonpolar solvents like benzene and hexane, AlBr3 has low solubility due to the absence of polar groups that can interact with the ionic compound. The solubility of AlBr3 in benzene is approximately 0.01 g/100 mL at room temperature.

In some other solvents like diethyl ether and carbon tetrachloride, AlBr3 has intermediate solubility due to the presence of both polar and nonpolar groups. For example, the solubility of AlBr3 in diethyl ether is approximately 36 g/100 mL at room temperature.

Overall, the solubility of AlBr3 in different solvents depends on the balance between the attractive forces between the solvent molecules and the AlBr3 ions, and the repulsive forces within the ions and solvent molecules.
