Difference Between Sodium Hydroxide and Aluminum Hydroxide
Both sodium hydroxide and aluminum hydroxide are ionic compounds consist of metal cations and hydroxide anions. The main difference between sodium hydroxide and aluminum hydroxide is that sodium hydroxide is a basic compound whereas aluminum hydroxide is an amphoteric compound.
What is the reaction between Aluminium and sodium hydroxide?Sodium aluminate is also formed by the action of sodium hydroxide on elemental aluminium which is an amphoteric metal. The reaction is highly exothermic once established and is accompanied by the rapid evolution of hydrogen gas.
