Is sulfur a sol?

Sulfur sols are colloidal solutions of elemental sulfur or of sulfur-rich compounds. Both types of sols are stabilized by the negative charge of the particles which results in mutual repulsion. Therefore, cations and especially multivalent cations are able to precipitate the sol particles.

How can we get sulphur sol in water?

Answer: A colloidal sol of sulphur can be obtained by passing hydrogen sulphide into solution of sulphur dioxide in water or through a solution of an oxidising agent.

Is sulphur a hydrophobic sol?

Sulphur sol is hydrophobic .

What is the nature of sulphur sol?

Sulphur sols are highly dispersed sols which contain about 0.08\% of sulphur. They are prepared by reduction of sulphur dioxide by hydrogen sulphide gas. It can also be obtained by passing extremely heated sulphur vapour into water that is air free. Large aggregates of Sulphur will be formed as S8 molecules.

How is sulphur sol prepared?

Explain preparation of sulphur sol and gold sol

1. Oxidation sulphur sol is prepared by passing H2S into SO2 H2S + SO2 → S (sol) + H2O.
2. Reduction of AuCl3 with formaldehyde gives gold sol. AuCl3+ HCHO + 3H2O → Au (sol) + 3HCOOH + 6HCl.

Which type of colloid is sulphur sol?

multimolecular colloid
– A sol of Sulphur is an example of a multimolecular colloid. A Sulphur sol contains particles of various sizes composed of about a thousand molecules of Sulphur.

When a sulphur sol is evaporated sulphur is obtain mixing with water sulphur sol is not formed the?

Hydrophobic sol are irreversible in nature. They have no affinity between the dispersed phase and the dispersion medium (H2O). Further once precipitated, they do not form the colloidal sol by simple addition of water.

When a Sulphur sol is evaporated Sulphur is obtain mixing with water Sulphur sol is not formed the?

When a Sulphur sol is evaporated Sulphur is obtained?

When a sulphur sol is evaporated, solid sulphur is left. On mixing with water no colloidal sol is formed.

How is gold sol prepared by chemical method?

To prepare the gold sol, electrodes of gold are taken into a cell and then an electric arc is supplied. The heat is generated which evaporates the metal. These metal particles are then condensed to form colloidal size gold particles.

How is gold sol prepared by reduction method?

Gold sols are producing by boiling a solution of tetrachloroauric acid with a reducing agent. At the beginning of the reduction process, gold atoms are liberated from the chloroauric acid. The gold atoms aggregate forming microcrystals.

Is sulphur sol An Associated colloid?

Sols are also a type of colloid. Complete step by step answer: – A sol of Sulphur is an example of a multimolecular colloid. A Sulphur sol contains particles of various sizes composed of about a thousand molecules of Sulphur.
