What happens when sulfur is mixed with water?

What happens when sulfur is mixed with water?

Sulfur is melted with superheated water (at 170 °C under high pressure) and forced to the surface of the earth as a slurry. Sulfur is mostly used for the production of sulfuric acid, H2SO4. Most sulfur mined by Frasch process is used in industry for the manufacture of sulfuric acid.

Does sulfuric acid dissolve in water?

Sulfuric acid is a colorless oily liquid. It is soluble in water with release of heat. It is corrosive to metals and tissue.

Why is it recommended that the acid should be added to water and not water to the acid?

Answer: The reaction of acid and water is an exothermic reaction since a lot of heat is liberated during the reaction. This heat changes some water to steam explosively which can splash the acid on our face or clothes and cause acid burns. As a result, adding acid to water is safe, but adding water to acid is not.

Why sulfur does not dissolve in water?

Sulfur (sometimes still spelled “sulphur”) is notoriously difficult to dissolve due to its nonpolar nature; even water, the “universal solvent,” is not capable of dissolving sulfur.

What can happen if you mix acid and water incorrectly?

Adding more acid releases more heat. If you add water to acid, you form an extremely concentrated solution of acid initially. So much heat is released that the solution may boil very violently, splashing concentrated acid out of the container! So Always Add Acid to water, and never the reverse.

What is dilute why care must be taken while mixing concentrated acid with water?

Dilution of concentrated acid is an exothermic process. If water is added to a concentrated acid, the heat generated may cause the mixture to splash out and cause burns. When the acid is added to water slowly with constant stirring, the mixture will not splash out.

When mixing acid and water which goes first?

After measuring out your concentrated acid and water, the acid must always be added to the water. This is because when the two mix, heat is generated – this is called the “Enthalpy of solution” or “enthalpy of dissolution”.

What happens when you mix sulfur and water?

Sulfur does not react with water. If you put the two together, the sulfur will float on the surface of the water or at best, the sulfur will get wet.

Why don’t sulphur and phosphorus react with water?

The only elements that do react with water are those that are easily ionised (like the alkali & alkaline earth metals) or have strong oxidising properties (fluorine, chlorine etc). Both sulphur & phosphorus have quite high ionisation energies and aren’t strong oxidisers, so won’t react.

How do you make sulfuric acid with water?

If you want sulfur to react with water you must first react sulfur with oxygen to form SO 2. The SO 2 will then react with water to form H 2 SO 3, sulfurous acid. To make sulfuric acid, you must allow the SO 2 to react with excess oxygen in the presence of a vanadium (V) catalyst to make SO 3.

Which element does not react with water?

Sulfur =it is element number 16 on the periodic table. Sulfur does not react with water because it is insoluble. Sulfur is a nonmetal and a yellow crystalline solid.
