Solution
When zinc granules are treated with dil.HCl, we get Zinc chloride and H2 gas
Zn +2 HCL- ---> ZnCl2 + H2
You get a standard metal - acid reaction occurring. The zinc is oxidised and passes into solution, whilst hydrogen ions are reduced. End products are zinc chloride and hydrogen gas (the latter can be ignited with a lighted taper or match at the mouth of the test tube)
Zn (s) + 2HCl (aq) → ZnCl2 (aq) + H2 (g)
small rise in temperature is found in this reaction
