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 the pH of 0.50 M H2S (given that Ka 8.91 108)?
The Ka value provided is for the dissociation of H2S into H+ and HS-. To find the pH of the solution, calculate the concentration of H+ ions produced when H2S dissociates. Using the Ka expression, set up an ICE table to determine the concentrations of H+, HS-, and H2S at equilibrium. Finally, use the concentration of H+ ions to calculate the pH of the solution.
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.
What is the formula for hydrosulfric acid?
The formula for hydrosulfuric acid is H2S.
How many moles of hydrogen sulfide are contained in a 64.6-g sample of this gas?
To find the number of moles of hydrogen sulfide, divide the given mass by the molar mass of hydrogen sulfide. The molar mass of hydrogen sulfide is approximately 34.08 g/mol. Thus, 64.6 g / 34.08 g/mol = 1.9 moles of hydrogen sulfide in the sample.
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.
How do you determining pH from weak acids?
H2S >> H+ + HS- Ka = [H+][HS-]/[H2S] Ka = 10^-7.0

How can you make h2s?
Add an acid to Na2S.It will emit H2S.
Is H2S ironic or covalent?
H2S is a polar compound.It is not ionic.
What is the fomula for hydrosulfuric acid?
Hydrosulfuric acid is H2S. H2S (aq) (H2SO4 is sulfuric acid). The acids with "hydro" at the start of their names are all derived from dissolved gases, e.g. hydrochloric acid is aqueous hydrogen chloride, hydrocyanic acid is aqueous hydrogen cyanide etc.
What is the formula for hydrosulfric acid?
The formula for hydrosulfuric acid is H2S.
Can H2S gas discolor carpeting?
H2S do not have bleaching properties.So it do not discolor
What is the state of h2s?
H2S is a gas.It smells like rotten eggs.
Is the compound h2s an acid?
It is known as hydrosulfuric acid. Not to be confused with sulfuric acid which is H2SO4
How can we make H2S in lab?
Add Na2S or K2S to an acid.It will give out H2S.
