The Zn2+ ion is hydrated and forms an acidic solution. A 10M solution has a pH of 1. Chlorohydroxy zincate ions are formed and a very simplified equation would be :-
ZnCl2 +4H2O -> ZnCl2(OH)2 + 2OH3+
the situation is more complex than shown above - depending on the molarity of the solution different zincate species predominate. The solubility of ZnCl2 in water is epic, 400 g in a 100 ml of water.
When zinc metal is mixed with ZnCl2 (zinc chloride), a redox reaction occurs. The zinc metal will react with the zinc ions in the zinc chloride solution to form zinc atoms, while the chloride ions will remain in solution. This reaction usually results in the formation of more zinc metal and zinc chloride.
When hydrochloric acid (HCl) is mixed with zinc, zinc chloride and hydrogen gas are formed. The reaction between HCl and zinc is a single replacement reaction where the zinc replaces the hydrogen in the acid to form zinc chloride and hydrogen gas.
Evidence that a chemical reaction took place when zinc mixed with HCl includes the production of hydrogen gas bubbles, formation of zinc chloride as a product, and an increase in temperature of the reaction mixture due to the exothermic nature of the reaction. Additionally, the disappearance of the solid zinc as it undergoes dissolution is another indication that a chemical reaction has occurred.
The precipitate formed when zinc chloride reacts with iron nitrate is zinc hydroxide. This is because when zinc chloride and iron nitrate are mixed, zinc hydroxide is insoluble in water and will precipitate out of the solution.
The grey deposit forms due to a displacement reaction between platinum chloride and zinc. The zinc displaces the platinum from the compound, depositing it as a grey solid. This reaction is a common method for extracting platinum from its compounds.
no it does not because it forms a production of gas

The reaction is not possible.

The mass of zinc chloride produced levels off because zinc chloride is formed from a stoichiometric reaction between zinc and chloride ions. Once all available chloride ions are consumed in the reaction, adding more zinc will not result in additional zinc chloride production. This saturation occurs because the reaction is limited by the quantity of the limiting reactant, which in this case is the chloride source. As a result, excess zinc does not contribute to further zinc chloride formation.
Zinc chloride is produced by the reaction of hydrochloric acid with zinc metal. Zinc dust is often used as a reducing agent in this reaction to produce zinc chloride. The byproduct of this reaction is hydrogen gas.
You will get a positive result for hydrogen because the reaction of zinc and hydrochloric acid produces zinc chloride and hydrogen. The chlorine atoms from the hydrochloric acid attach to the zinc, leaving the hydrogen behind and thus, you have hydrogen.
When zinc is added to sodium chloride, a displacement reaction occurs where the zinc replaces the sodium in the compound. This results in the formation of zinc chloride and sodium being left separate.
When sodium chloride (NaCl) reacts with zinc (Zn), the chemical reaction produces zinc chloride (ZnCl2) and releases sodium metal (Na).
