       Both Acidic and Basic: BeO

BeO also is soluble in basic solution (right). The hydroxide ions tear the BeO crystal apart by attacking ions more strongly than water molecules can:

The oxide ions then are freed to interact with water molecules :

The overall reaction is the sum of the two:

This is the species that was mentioned previously as being most stable in basic solution, where a shortage of ions exists.
