Zn + NaCl → ZnCl₂ + Na
- Zn is solid (s)
- NaCl is salt (ppt.)
- ZnCl₂ is salt (ppt)
- Na is solid (s)
Why in ZnCl₂, chlorine have 2 atoms?
→ Zn (Zinc) have valency of 2+, which means that it can break to give 2 electrons.
Thus to have a stable reaction, the chlorine which have 1- valency had two be twice in quantity.
What type of reaction it is?
→ This is displacement reaction because element displaces other element from a compound.
