Why is H2S acidic in water?
H2S is acidic in water because it can dissociate to form H+ ions, which can lower the pH of the solution. When H2S reacts with water, it forms hydrosulfuric acid (H2S + H2O → HS- + H3O+), which can donate a proton to water, increasing the concentration of H3O+ ions and making the solution acidic.
Is h2s gas acidic in nature?
Yes, hydrogen sulfide (H2S) gas is acidic in nature. When dissolved in water, it forms hydrosulfuric acid, which ionizes to release hydrogen ions, making the solution acidic.
What is the pH of a solution containing H2S?
The pH of a solution containing H2S would be acidic, as H2S is a weak acid. The exact pH value would depend on the concentration of H2S in the solution.
What is H2S an acid base or salt?
it is a gas which in water shows the acidic property.
Why h2s is acidic and h2o is neutral?
H2S is only acidic in reference to water(!). Of coarse H2O is neutral referred to water because it is the S A M E .Even water can be both acid A N D base at the same time, though a bit weaker acidic than H2S, but a bit more stronger base.

Is there ever any damage with H2S gas?
Yes - nearly always. H2S is a toxic gas and quite corrosive - slightly acidic.
What is H2S an acid base or salt?
it is a gas which in water shows the acidic property.
In H2S determination with iodometry (by iodine and thiosulfate - and H2s dissolved in Borax) why we add HCl to iodine before adding borax?
HCl is added to iodine in the iodometric determination of H2S to ensure that the iodine is in an acidic medium, which helps to prevent the formation of iodine complexes that could interfere with the reaction. The acidification promotes the conversion of H2S to the more easily oxidized species, allowing for a more accurate measurement of H2S concentration. Additionally, the acidic environment aids in the proper dissolution of iodine, ensuring that it reacts effectively with any H2S present in the sample.
Why h2s is acidic and h2o is neutral?
H2S is only acidic in reference to water(!). Of coarse H2O is neutral referred to water because it is the S A M E .Even water can be both acid A N D base at the same time, though a bit weaker acidic than H2S, but a bit more stronger base.
Is h2s a strong electrolyte?
No, carbonic acid (H2CO3) is a weak acid, as it only partially dissociates in water solution. Thus, it is not a strong electrolyte.
Why H2S is more acidic than H2O?
Because S has a larger atomic radius than O, the conjugate base of hydrogen sulphide is more stable than the conjugate base of water. S is more polarizable. Also, SH- is a much weaker base than OH- (a strong base).
Chemistry reapeted questions every year 2nd pu?
when h2s is passed in to acidic solution containing zn2+ and cu2+ ions,cus precipitates but zns does not.give reason
Can anions be classified as acidic or basic?
Anions of acids are (at least) basic(eg. CH3COO- + H+ --> CH3COOH)but some anions are amphoteric, so partially acidic and partially basic(eg. acidic: HS- --> S2- + H+ ,and basic: HS- + H+ --> H2S)
How can you make h2s?
Add an acid to Na2S.It will emit H2S.
