Physical Properties of Tetraoxosulphate(VI) Acid:

1. Tetraoxosulphate(VI) acid is a colourless, viscous oily liquid.

2. It is very corrosive and causes severe burns when it comes in contact with human skin.

3. It has a densityDensity is the measurement of how tightly a material is packed together i.e. how closely the particles are packed in the material. The tighter the material is packed the more its... More of 1.84 gcm^-3 .

4. It has a boiling point of 338°C.

6. It is a hygroscopic substance.

Chemical Properties of Tetraoxosulphate(VI) Acid:

Action as an Acid:

In dilute solution, tetraoxosulphate(VI) acid is a strong dibasic acid. In an aqueous solutionA solution in which the solvent is water is referred to as an aqueous solution. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. For... More, it ionizes completely to form H⁺ and SO₄ ^2- . It neutralizes bases to form salts and water.

H₂ SO_4(aq) → 2H⁺ _(aq) + SO₄ ^2- _(aq)

Action on Metals:

Dilute tetraoxosulphate(VI) acid solution reacts with metals such as zinc to form salt and liberate hydrogen.
