What happens when zinc reacts with hydrogen sulphide?
It is known that hydrogen sulfide reacts with zinc oxide to form zinc sulfide according to Eq. 4.
What does zinc chloride and hydrogen sulfide make?
Explanation: Zinc sulfide react with hydrogen chloride to produce zinc chloride and hydrogen sulfide.

What is the reactivity of hydrogen sulfide?
Hydrogen sulfide (H2S) is a foul-smelling (rotten egg odor) very reactive gas that is highly toxic. If the depositional environment is anaerobic, bacterial sulfate reduction can produce small quantities of H2S.
Which gas is produced when dilute hydrochloric acid is added to zinc sulphide?
When dilute hydrochloric acid is added to granulated zinc placed in a test tube, zinc metal is converted to zinc chloride and hydrogen gas is evolved in the reaction. In the reaction we can see that a zinc chloride salt is formed and hydrogen gas is evolved. The evolved hydrogen gas is colourless and odourless.
Which Colour PPT is formed when H2S gas is passed through Zn2+ ion solution?
Formation of Zn2+ ions among the products can easily be judged when the blue colour of the solution due to Cu2+ has disappeared. If H2S gas is passed through the colorless solution containing Zn2+ ions, appearance of white zinc sulphide, ZnS can be seen on making solution alkaline with ammonia.
What happens when ZnS reacts with HCl?
Zinc being the reactive element reacts with an aqueous solution of hydrogen chloride to form a salt zinc chloride and a byproduct hydrogen gas. Thus, when HCl (aq) reacts with Zn(s), salt and hydrogen gas is formed.
What is the Colour of zinc sulphide?
Zinc sulfide appears as a yellowish-white powder in a liquid.
What is ZnS called?
Zinc sulfide
Zinc sulfide, ZnS, occurs in nature as the mineral sphalerite and may be prepared by treating solutions of zinc salts with hydrogen sulfide.
How does zinc sulfate react with hydrogen sulfide?
Zinc sulfate react with hydrogen sulfide ZnSO 4 + H 2 S → ZnS + H 2 SO 4 [ Check the balance ] Zinc sulfate react with hydrogen sulfide to produce zinc sulfide and sulfuric acid.
What happens when you mix ZnS with H2S?
ZnS + 2HCl → ZnCl 2 + H 2 S [ Check the balance ] Zinc sulfide react with hydrogen chloride to produce zinc chloride and hydrogen sulfide. Hydrogen chloride – concentrated solution.
What happens when zinc metal reacts with hydrochloric acid?
The metal zinc readily reacts with hydrochloric acid to produce hydrogen gas (H2) and zinc chloride (ZnCl2). The reagents are zinc and hydrochloric acid, and the sum is 0 + 2 * ( -167.2) = -334.3.
What happens when H 2 s reacts with sulfur?
In this reaction hydrogen takes electrons and involve in reduction part. If H 2 S reacts with some metals which have lower activity such as Cu , Ag . In such reactions, hydrogen gas and the metal sulfide can be obtained. The oxidation number of sulfur remains constant while hydrogen changes from +1 to 0.
