Sulphuric Acid
H2SO4(aq) + CaI2(aq) -> CaSO4(s) + 2HI(aq)
The balanced equation for the reaction between sulfuric acid (H2SO4) and calcium sulfide (CaS) in aqueous solution is: H2SO4(aq) + CaS(aq) → CaSO4(s) + H2S(g)
H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O
2H+ + SO42- + Ca2+ + 21 > CaSO4 + 2H+ + 21-
CdS(s)+H2SO4(aq)--> Cd2SO4(aq)+H2S(g) one of the byproducts of this reaction will be gas Hydrogen Sulfide, H2S
