The reaction between tin and hydrochloric acid
The chloride formed when tin reacts with hydrochloric acid is tin (II) chloride, also known as tin dichloride.
Tin | + | Hydrochloric acid | → | Tin (II) chloride | + | Hydrogen |
Sn | + | 2HCl | → | SnCl2 | + | H2 |
Tin reacts with dilute acids slower than many other metals and heat is often required to speed up the reaction. This property means tin can be used as a protective coating on other, more reactive, metals.
