The chemical equation Sn + 2HCl -> SnCl2 + H2

  1. The chemical equation above shows that when tin (Sn) reacts with hydrochloric acid (HCl), it will form SnCl2 (tin(II) chloride) and hydrogen gas (H2).

  2. Reaction conditions: The reaction takes place under standard temperature and pressure conditions and in a hydrochloric acid environment.

  3. Reaction process: Tin, a metal, reacts with hydrochloric acid, resulting in tin(II) chloride and hydrogen gas. This process is a substitution reaction, in which tin replaces hydrogen atoms in hydrochloric acid to form salt and hydrogen gas.
    Sn (s) + 2HCl(aq) -> SnCl2(aq) + H2(g)

  4. Phenomenon occurred: When tin reacts with hydrochloric acid, we observe the phenomenon of hydrogen gas bubbles escaping. The color of the solution also changes due to the formation of tin(II) chloride. The complete process occurs when there are no more gas bubbles escaping from the solution.
