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.
Zinc carbonate + Hydrochloric acid =Zinc chloride + Carbonic acid.
It is a double displacement reaction
Solid Zinc reacting with Hydrochloric Acid is a single replacement Oxidation/Reduction reaction.
Many do react with hydrochloric acid. An example is the reaction between zinc and hydrochloric acid, which produces zinc chloride and hydrogen gas. Zn + 2HCl --> ZnCl2 + H2
zinc plus hydrochloric acid produces hydrogen and zinc chloride Zn + 2HCl -> H2 + ZnCl2 + Bananas-Apples ZnhI28hnd7777+1=PLUM
double-displacement reaction
Is aqueous copper (2)sulphate an effective catalyst in the reaction between zinc and hydrochloric acid.
Solid Zinc reacting with Hydrochloric Acid is a single replacement Oxidation/Reduction reaction.
you can use the hydrochloric acid to differentiate between the zinc carbonate and zinc chloride as the zinc carbonate will give effervescence and the gas produced (carbon dioxide) turns lime water milky..and the zinc chloride will give no ppt
Carbon Dioxide
It is a single displacement reaction.
hcl+znco3----->zncl+hco3
Many do react with hydrochloric acid. An example is the reaction between zinc and hydrochloric acid, which produces zinc chloride and hydrogen gas. Zn + 2HCl --> ZnCl2 + H2
zinc sulphate is made of a reaction between zinc and what acid
zinc plus hydrochloric acid produces hydrogen and zinc chloride Zn + 2HCl -> H2 + ZnCl2 + Bananas-Apples ZnhI28hnd7777+1=PLUM
double-displacement reaction
sheet
ZnCO3 + 2HCl = ZnCl2 + H2O +CO2
Is aqueous copper (2)sulphate an effective catalyst in the reaction between zinc and hydrochloric acid.
