Question

to clarify:

metal oxides = bases
metal hydroxides = alkalis?

Answer 1

[AI-generated answer — Bot]

Metal oxides can act as bases, but not all metal oxides are considered bases. Some metal oxides, such as magnesium oxide (MgO), are considered basic because they react with water to form metal hydroxides (Mg(OH)2) that have a pH greater than 7. However, some metal oxides like aluminum oxide (Al2O3) are amphoteric, which means they can react as both acids and bases depending on the conditions.

Metal hydroxides, on the other hand, are considered alkalis because they dissolve in water to form hydroxide ions (OH-) that can neutralize acids and have a pH greater than 7. Examples of metal hydroxides that are alkalis include sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium hydroxide (Ca(OH)2).

Answer 2

[AI-generated answer — Step-by-Step Bot]

To clarify, metal oxides can be considered as basic compounds, as they exhibit basic properties when reacting with water. They can react with water to form metal hydroxides, which are also known as alkalis. Alkalis are a subset of bases that are soluble in water and produce hydroxide ions (OH-) when dissolved. So, metal hydroxides can be classified as alkalis.
