Re: influence of HCl on the aqueous solution of H2S
H 2 S + (CH 3 COO) 2 Pb → 2 CH 3 COOH + PbS↓
that is OK?
that is OK?

Re: influence of HCl on the aqueous solution of H2S
Reaction on lead acetate paper that turns black by PbS.
It's OK?
H2S + (CH3COO)2Pb → 2CH3COO + PbS↓

Re: influence of HCl on the aqueous solution of H2S
Are the following description and drawing correct?
Reaction on wet indicator paper
H2S + H2O = HS + H3O
Observations:
There is gas coming out of the test tube with a characteristic smell.
Universal test strip turns red when wet.
Conclusions:
The gas that evolves is hydrogen sulfide

Re: influence of HCl on the aqueous solution of H2S
is this the correct form of the equation ?
HCl + HS(-) + H3O(+) -> Cl(-) + H3O(+) + H2S↑
HCl + HS(-) + H3O(+) -> Cl(-) + H3O(+) + H2S↑

Re: influence of HCl on the aqueous solution of H2S
aqueous solution of H2S:
H2S + H2O → H2SO4
2HCl + H2SO4 → Cl2 + SO2 + 2H2O
Are such equations correct?
H2S + H2O → H2SO4
2HCl + H2SO4 → Cl2 + SO2 + 2H2O
Are such equations correct?
