The surface area is a big help
When nitrogen and aluminum form an ionic bond, the formula of the ionic compound is AlN.
Aluminum forms a cation Al⁺³ and nitrogen forms an anion N⁻³. When each cation of Al⁺³ combines with an anion of N⁻³, AlN or aluminum nitride is formed. In AlN a strong electrostatic force of attraction exists between the oppositely charged Al⁺³ and N⁻³ ions.
So the solution inside doesn't splash
What is the exoeruent. Searched it up on google and only came up with two search results. None related to chemistry
Precipitation hope this helped you
