Zinc sulfide It is easily produced by igniting a mixture of zinc and sulfur. Since zinc sulfide is insoluble in water, it can also be produced in a precipitation reaction. Solutions containing Zn 2+ salts readily form a precipitate ZnS in the presence of sulfide ions (e.g., from H 2 S). Zn 2+ + S 2− → ZnS. This reaction is the basis of a gravimetric analysis for zinc.

- In external circuit it is observed that the flow of electrons takes place from Zn to H. Thus it concludes that the electrons must have originated from Zn i.e. it is oxidized and it is anode and it is negative with respect to hydrogen electrode. Thus standard reduction potential of zinc is - 0.76V.

- If the overall potential for the reaction between zinc and acid is 0.76 volts, and the half-cell potential for the reduction of H + ions is 0 volts, then the half-cell potential for the oxidation of zinc metal must be 0.76 volts.

- Acid rain is formed when nitrogen oxides or sulfur oxides in the atmosphere react with suspended water droplets and produce acids. The chemical reaction equation for the production of acid rain resulting from sulfur oxides is: SO2 + HOH -> H2SO3. The reaction equation for acid rain produced from nitrogen oxides is: 2NO2 + HOH -> HNO2 + HNO3.

Hydrogen sulfide Hydrogen sulfide and oxygen burn with a blue flame to form sulfur dioxide (SO 2) and water. In general, hydrogen sulfide acts as a reducing agent. At high temperature or in the presence of catalysts, sulfur dioxide can be made to react with hydrogen sulfide to form elemental sulfur and water. This is exploited in the Claus process, the main way to convert hydrogen sulfide into elemental sulfur.

Zinc sulfide Zinc sulfide. Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite. Although this mineral is usually black because of various impurities, the pure material is white, and it is widely used as a pigment.

- Procedure to activate zinc dust: 1. Measure out 0.060 g zinc dust, put in a medium sized test tube. 2. add 2 drops of water (distilled) 3. add 6 drops of 3M HCl, you should see bubbles if you do not add more HCl. 4. let this react for 30 seconds. 5. add water until the zinc settles to the bottom of the test tube.

Sulfur Dioxide Sulfur dioxide (SO2) is a gas that is prevalent in crude oil, coal, and ore that contains common metals like aluminum, copper, zinc, lead and iron. Where does it come from?O2 is formed when fuel-containing sulfur is burned and when gasoline is extracted from oil, or when metals are extracted from ore. Once it is released into the atmosphere, SO2 dissolves in water vapor to form acid (acid rain).

What happens when zinc reacts with water? Zinc metal does not react violently with water. It hardly oxidises under normal conditions. A coating of zinc (called galvanising) is used to protect steel from rusting.Zinc has a coating of the oxide that protects it from reaction with oxygen.It becomes vulnerable to oxidation in the presence of other substances that weaken its oxide layer. Acids will quickly dissolve zinc, as will alkalies. Acids produce zinc 2+ cations, whereas alkalies produce zincate ZnO2(2-) anions.inc has a coating of the oxide that protects it from reaction with oxygen.
