The chemical equation for the reaction that occurs when zinc metal is added to a solution of copper II chloride is:
Zn + CuCl2 -> Cu + ZnCl2.
The chemical equation is:
Zn + CuCl2 = ZnCl2 + Cu
I think it turns from brown to a silver color
This equation is CaO + 2 HCl -> CaCl2 + H2O.
NaCl(aq) + AgNO3(aq) --> NaNO3(aq) + AgCl(s) This is an example of a double replacement/displacement reaction.
When Ammonia solution is added to Copper sulphate, at first a precipitate of Copper hydroxide is formed. If excess ammonia is added, finally a deep bluish solution of Tetraamine Copper(II) Sulfate is formed
the solution changes to a white percipitate. Ionic Equation= Ag(+) + 2Cl(-) -----> AgCl(2) === ===
Sodium chloride solution is corrossive for aluminium; first a layer of of aluminium oxide is formed.
I think it turns from brown to a silver color
The chemical reaction is:CuCl2 + H2SO4 = CuSO4 + 2 HCl(g)The gas is hydrogen chloride.
(NH4)2C2O4(aq) + CaCl2(aq) yields CaC2O4 +2NH4Cl(aq)
This equation is CaO + 2 HCl -> CaCl2 + H2O.
NaCl(aq) + AgNO3(aq) --> NaNO3(aq) + AgCl(s) This is an example of a double replacement/displacement reaction.

No colour
the solution changes to a white percipitate. Ionic Equation= Ag(+) + 2Cl(-) -----> AgCl(2) === ===
If chloride is present silver chloride with get precipitated..
You will obtain a sodium chloride solution in water.
Sodium chloride is added to increase the viscosity of the solution.
