No,it is not acidic.It is a basic oxide.

Magnesium Oxide
Acidic oxides typically contain nonmetals and react with water to form acids, such as sulfur dioxide (SO2) and nitrogen dioxide (NO2). Basic oxides contain metals and react with water to form bases, like sodium oxide (Na2O) and magnesium oxide (MgO).
When magnesium oxide is tested with red litmus paper, there will be no observable change because magnesium oxide is a neutral substance. It does not exhibit any acidic or basic properties that would cause a color change in the red litmus paper.
Magnesium oxide is formed when magnesium metal reacts with oxygen. It is an oxide of magnesium. Magnesium is the metal, and magnesium oxide is the resulting compound formed when magnesium reacts with oxygen.
When magnesium ribbons are burned, they react with oxygen in the air to form magnesium oxide ash (MgO). This ash is a white, powdery substance that is the result of the oxidation of magnesium.
Zinc oxide reacts with metallic magnesium to produce magnesium oxide and metallic zinc.
magnesium oxide
Magnesium + copper oxide --> magnesium oxide + copper
The difference is magnesium oxide contains oxide ions ,whereas aluminium oxide doesn't.
Magnesium and oxygen combine to form magnesium oxide (MgO). Magnesium oxide is a white solid that occurs naturally as the mineral periclase. It is commonly used in various industrial applications, including as a refractory material and in the production of ceramics.
Iron and magnesium oxide can react chemically to form iron(II) oxide and magnesium metal. The reaction occurs when iron is heated with magnesium oxide in a high temperature environment, leading to the transfer of oxygen from magnesium oxide to iron.
