Displacement reaction
Displacement reactions are those in which a more reactive element removes a less reactive element from its compounds.
When one element in a compound replaces another, it causes a single displacement reaction. A metal can only replace another metal, and a nonmetal can only replace another nonmetal. The other element cannot be replaced except by a more reactive component of the chemical with which it reacts.
The reaction of Aluminum with Sodium hydroxide:
The reaction of Aluminum with Sodium hydroxide (Al + NaOH) produces a salt and Hydrogen gas.
2Al (s) + 2NaOH (l) + 6H2O (l) → 2Na[Al(OH)4](s) + 3H2(l)
This reaction is a displacement reaction because Aluminum removes Sodium from its compound.
Summary:
What type of reaction is Al + NaOH? What are the products formed?
Al + NaOH is a displacement reaction where sodium is displaced by aluminum. Salt and hydrogen gas are the end results of the process. A single displacement reaction, often referred to as a single replacement reaction, replaces one element in a compound with another. An oxidation-reduction reaction is the sort of chemical process in question.
