To dilute HCl for preparing H2S gas, you can slowly add concentrated HCl to water, as it is exothermic and can generate heat. Be cautious and always add acid to water, not the other way around. Diluted HCl can then be used to react with a sulfide salt to liberate H2S gas.

What gas is formed when HCl is added to Na2S?
When HCl is added to Na2S, hydrogen sulfide gas (H2S) is formed. This gas has a characteristic rotten egg smell and is toxic in high concentrations.
What is released when Na2S and HCl mix?
When Na2S and HCl mix, they react to form hydrogen sulfide (H2S) gas, sodium chloride (NaCl), and water (H2O). H2S is a colorless gas with a characteristic foul smell similar to rotten eggs.
What happens if aluminum is added in dilute hcl?
When aluminum is added to dilute hydrochloric acid (HCl), a chemical reaction occurs. The aluminum reacts with the HCl to form aluminum chloride and hydrogen gas. The reaction is exothermic and produces bubbles of hydrogen gas as it proceeds.
Why no gas is released when sulphur is added to dilute hcl?
When sulfur is added to dilute hydrochloric acid (HCl), no gas is typically released because sulfur is a non-reactive element and does not readily react with HCl to produce a gas. Sulfur can only react with strong oxidizing agents, such as concentrated nitric acid or hot concentrated sulfuric acid, to release sulfur dioxide gas.
What happens when Sulphur reacts with HCl?
When sulfur reacts with HCl (hydrochloric acid), a chemical reaction takes place producing hydrogen sulfide gas (H2S) and sulfur dichloride (S2Cl2) as products. The reaction can be represented by the following equation: S + 2HCl -> H2S + S2Cl2.
What gas is formed when HCl is added to Na2S?
When HCl is added to Na2S, hydrogen sulfide gas (H2S) is formed. This gas has a characteristic rotten egg smell and is toxic in high concentrations.
What volcanic gas is released the most by volcanoes?
Volcanoes release H2S, HCl, SO2, CO2, etc.
What is released when Na2S and HCl mix?
When Na2S and HCl mix, they react to form hydrogen sulfide (H2S) gas, sodium chloride (NaCl), and water (H2O). H2S is a colorless gas with a characteristic foul smell similar to rotten eggs.

Which gas is evolved when few pieces of marble is added to dilute HCl?
When marble (calcium carbonate, CaCO3) is added to dilute hydrochloric acid (HCl), carbon dioxide gas (CO2) is evolved due to the reaction between the acid and the carbonate compound. This gas can be observed as bubbles coming out of the solution.
How do you prepare H's gas through keeps apparatus?
This question may be about preparing H2S (or maybe hydrogen) with Kipp's apparatus.
Which thing gives colourless gas that burns with pop sound on reaction with dilute hcl?
Zinc metal gives off a colorless gas (hydrogen gas) that burns with a pop sound when reacted with dilute hydrochloric acid.
What is the balanced equation for the reaction of ammonia vapor and hydrogen sulfide gas react to produce solid ammonium sulfide?
The balanced equation for the reaction is: 2NH3(g) + H2S(g) → (NH4)2S(s)
Color of zinc granules after reaction with dilute hcl?
The zinc granules will appear shiny and metallic before the reaction with dilute HCl. After the reaction, the zinc granules will dissolve, producing colorless zinc chloride solution and releasing hydrogen gas.
What type of reaction is fes 2hci feci2 h2s?
This is a double displacement reaction. Iron(II) sulfide (FeS) and hydrochloric acid (HCl) react to form iron(II) chloride (FeCl2) and hydrogen sulfide gas (H2S).
