A metal oxide will form an acid when it is dissolved in water.
T/F
Na2O + 2H2O ==> 2NaOH
True
False. A metal oxide will form a base when it is dissolved in water, not an acid.
False.
To determine whether a metal oxide will form an acid when dissolved in water, we need to consider its chemical composition. Metal oxides that dissolve in water usually form bases, not acids. These metal oxides are referred to as basic oxides.
When a metal oxide dissolves in water, it reacts with water molecules to produce hydroxide ions (OH-) which are responsible for the basic properties. The general equation for this reaction is:
Metal Oxide + Water → Metal Hydroxide
For example, when sodium oxide (Na2O) dissolves in water, it produces sodium hydroxide (NaOH):
Na2O + H2O → 2NaOH
Therefore, when a metal oxide dissolves in water, it typically forms a base, not an acid.
