Salts and Neutralization

Question 1

How does a salt get formed from neutralization?

Answer 1

Acid + base or alkali = Salt + Water
HCl + NaOH = NaCl( Salt) + H2O
Thus : Neutralization is the reaction between and acid and a Base/Alkali to form a salt and water

Question 2

What are Acidic Oxides? and why?

Answer 2

They are the oxides of Non metals.
They are called that because they react with water to form and acid
SO2 + H2O = H2SO3

Question 3

What happens when acidic oxides react with alkalis?

Answer 3

They react to from Salt and water

CO2 + 2NaOH = Na2CO3 + H20

Question 4

What are Basic Oxides? and explain their reactions with Acids

Answer 4

They are the oxides of metals.
They react with Acids to form salts and water
CaO + 2HCl = CaCl + H2O

Question 5

What are Amphoteric Oxides? and explain their reactions.

Answer 5

They are oxides that react with acids and alkalis both to form Salt + Water
For eg. Aluminum Oxide : Al2O3
Aluminum Oxide + Hydrochloric acid = Aluminum Chloride + Water
AND
Aluminum Oxide + Sodium Hydroxide = Sodium Aluminate + Water

Question 6

What are neutral oxides ?

Answer 6

They react with neither acid nor bases therefore not forming
Eg. watr and carbon monoxide
