How does hydrogen sulphide look?
Hydrogen sulphide, H2S, is a colorless and poisonous flammable gas.
What happens when hydrogen sulphide passes through cadmium chloride?
when H2S gas i.e. hydrogen sulphide gas is passed through cadmium chloride solution, yellow colored precipitate of cadmium sulphide (CdS) is formed and aqueous hydrochloric acid (HCl) is formed. H2S(g) + CdCl2(aq) -----> CdS(s) + 2HCl(aq)
Why does silver turn black?
silvers turn black due to the reaction of sulphur present in hydrogen sulphide from air. --- Tarnish is silver oxide (rust) caused by a chemical reaction of oxygen and hydrogen sulphide with the surface of the silver. Unlike iron, silver will not rust in air absent of hydrogen sulphide.
Why is hydrogen sulfide used to restore the color of old paintings?
Hydrogen sulphide is a toxic gas; also dangerous for paintings containing lead colours and for objects made from silver. You think probably to hydrogen peroxide (H2O2), used for restoring.. Lead (II) trioxocarbonate (IV) in white Lead (II) paint is converted to lead (II) Sulphide by atmospheric Hydrogen Sulphide. This reaction darkens the colour of the Paint. Hydrogen Peroxide is added to the Paint to restore the colour where it oxidizes the Lead (II) Sulphide to Lead (II) tetraoxosulphate (VI).
What is the equation of sulphide with barium chloride solution?
S2- + BaCl2 ------> BaS + 2Cl-
What is the reaction of barium sulphide on nitric acid?
Barium sulphide reacts with nitric acid to produce barium nitrate and hydrogen sulphide gas. The balanced chemical equation for this reaction is BaS + 2HNO3 -> Ba(NO3)2 + H2S. It is important to carry out this reaction in a well-ventilated area to avoid inhaling the toxic hydrogen sulphide gas.
What happens when calcium sulphide reacts with hydrochloric acid?
When calcium sulphide reacts with hydrochloric acid, it forms calcium chloride and hydrogen sulphide gas. The balanced chemical equation for the reaction is CaS + 2HCl → CaCl2 + H2S. Hydrogen sulphide gas being released gives off a rotten egg smell.
Is chlorine a constituent of gobar gas?
There is no chlorine in gobar gas or bio gas. The gases present are methane, carbon dioxide, nitrogen, hydrogen and hydrogen sulphide
What type of chemicalreaction is between hydrogen sulphide and oxygen?
Displacement reaction
The corrosion of the metal is an example of?
A reaction with oxygen, water, hydrogen sulphide, acids, bases
Is the hydrogen sulphide ionic compounds?
No. Hydrogen sulphide is covalent.
What is the reaction between sodium zincate and hydrogen sulfide gas?
The reaction between sodium zincate (Na2Zn(OH)4) and hydrogen sulfide gas produces zinc sulfide (ZnS) and water. The balanced chemical equation for the reaction is: Na2Zn(OH)4 + H2S -> ZnS + 2NaOH + H2O
How many hydrogen atoms are in hydrogen sulphide?
There are two atoms.Formula for hydrogen sulphide is H2S.
What will be balanced chemical equation for the action of ethyl chloride on potassium hydrogen sulphide?

What is the chemical equation for smelting copper sulphide?
The chemical equation for smelting copper sulphide is: Cu2S (copper sulphide) + O2 (oxygen) → 2Cu (copper) + SO2 (sulfur dioxide). This reaction is typically carried out in a furnace at high temperatures.
Is hydrogen sulphide a liquid?
Hydrogen sulphide (H2S) is a gas at room temperature.
What happens when hydrogen sulphide is mixed with oxygen?
Hydrogen sulphide explodes when it is mixed with oxygen.
