If you look on the pH scale, water is neutral, so adding magnesium oxide will turn the water from neutral to an alkali. I hope this helped:)

There is no new product being formed, eg. its just sugar plus water. It's not like a new substance is being formed. For example a chemical change could be Iron and oxygen, which forms something new, which is Iron Oxide. Get it?? :)
It reacts with acids, it dissolves exothermically in water to produce a basic solution.

When water is mixed with a metallic oxide, a metal hydroxide is typically formed. This reaction is known as a neutralization reaction, which involves the combination of the hydroxide ion from water with the metal ion from the metallic oxide.
When water is added to a metallic oxide, it forms a metal hydroxide (also known as basic oxide) and releases heat in an exothermic reaction. For example, when water is added to calcium oxide, it forms calcium hydroxide.
When a metallic oxide dissolves in water, it forms a basic solution due to the release of hydroxide ions. This process is also known as hydrolysis. The hydroxide ions react with water molecules to increase the pH of the solution.
When potassium oxide (K2O) dissolves in water, it forms potassium hydroxide (KOH), which is a strong base. This reaction releases heat and is exothermic. Potassium hydroxide dissociates in water to produce potassium ions (K+) and hydroxide ions (OH-).
This is a possible way to get an oxy-acid: CO2 + H2O --> H2CO3

When a non-metal oxide dissolves in water, it forms an acidic solution. This is because non-metal oxides react with water to produce acidic compounds such as hydrogen ions. This makes the solution acidic and capable of conducting electricity.
Metallic oxides are basic in nature, because when metallic oxide dissolves in water it forms corresponding base, which turns red litmus to blue.Those metallic oxide which dissolve in water are known as alkali, while those which do not dissolve in water are known as base
When an acid reacts with an oxide, it typically forms a salt and water. The acid will donate a proton (H+) to the oxide, forming a salt and water as the products of the reaction. The specific salt formed will depend on the acid and oxide involved in the reaction.

Lithium oxide is a basic oxide: When it dissolves in pure water, the resulting solution has a pH value greater than 7.0.
When a metal oxide reacts with an acid, a salt and water are formed as products. Additionally, carbon dioxide gas may be produced if the metal oxide is a carbonate.
