comparison and differentiate physical and chemical properties of aluminium,aluminium oxide and aluminium chloride

Solutions

Expert Solution

Aluminium:

At room temperature it is a metal, It appears as a silvery-white, soft, nonmagnetic and ductile metal.

Reacts with strong acids and evolves hydrogen gas. 2Al + 6 HCl → 2AlCl₃ + 3 H₂

corrosion resistant metal.

Aluminium oxide:

Aluminium oxide (Al₂O₃), is a white solid amorphous compound, also called as alumina (used as a stationary phase material in chromatography). Aluminium oxide is an amphoteric substance, meaning it can react with both acids and bases.

Al₂O₃ + 6 HF → 2 AlF₃ + 3 H₂O

Al₂O₃ + 2 NaOH + 3 H₂O → 2 NaAl(OH)₄

Aluminium chloride:

Aluminium chloride has chemical formula AlCl₃, white amorphous salt that is highly soluble in water, acidic in nature when hydrolyzed and conducts electricity, reacts with strong bases and forms white aluminium hydroxide as a precipitate.

AlCl₃ + 3 NaOH → Al(OH)₃ + 3 NaCl
