What happens when magnesium oxide is put in water?
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:)
How do salt formed?
salts are formed when sea water evaporates. When the sea waters evaporate, the salt is settled down but the water molecules alone go and mix in the air. So, salt is formed.
What product is formed when alkali metals are heated with oxygen?
Improve Alkali Metal + Water ------> Alkali Hydroxide + Hydrogen Alkali Metal Oxide + Water ------> Alkali Hydroxide + Water
When sugar dissolves in water how can you tell it's not a chemical change?
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?? :)
Why is calcium oxide described as a base?
It reacts with acids, it dissolves exothermically in water to produce a basic solution.
What is formed when water is mixed with metallic oxide?
With some oxides metallic hydroxides are formed.
What substance is formed when water is added to metallic oxide?
when wate ris adde to metallic oxide it forms a hard substance
What substances are formed when potassium oxide dissolves in water?
When potassium oxide is dissolved in water it forms potassium hydroxide.
How will you show that metals form basic oxides?
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
What happens when a metallic oxide dissolves in water?
metallic oxide react with water to form its hydroxides. all these metal oxide are basic in nature due to more electropositive nature of metal atom. EX. M2O + H2O --> 2MaOH The alkali metal oxides M2O (M = Li, Na, K, Rb) Na2O + H2O --> 2NaOH sodium oxide dissolve in water afford sodium hydroxide
Is ammonia and ammonium hydro oxide are same?
No: The formula of ammonia is NH3 and the formula of ammonium hydroxide is NH4OH. The latter is formed spontaneously when ammonia dissolves in water.
What happens when magnesium oxide is put in water?
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:)

What name is given to basic oxides which can dissolve in water?
a basic oxide that dissolves in water is called an alkali
What product is formed when alkali metals are heated with oxygen?
Improve Alkali Metal + Water ------> Alkali Hydroxide + Hydrogen Alkali Metal Oxide + Water ------> Alkali Hydroxide + Water
Is lithium oxide a basic or acidic oxide?
Lithium oxide is a basic oxide: When it dissolves in pure water, the resulting solution has a pH value greater than 7.0.
What happens when magnesium oxide is added to water the salt will be?
Magnesium oxide react with water and magnesium hydroxide is formed.
