Yes!!!!

MgO (Magnesium oxide ) is a base, because it is a Group 2 metallic oxide.

An Alkali is a soluble base.

So if MgO is dissolved in water it forms the alkali magnesium hydroxide.

MgO(s) + H2O(l) = Mg(OH)2(aq)

NB Note the use of brackets in Mg(OH)2. This indicates that there are two hydroxide anions in the molecule. Writing as MgOH2 (No brackets) is INCORRECT, because it only indicates 1 x oxygen present , when there are actually 2 x oxygens in the molecule.
