What happens when HCl is added to Na2CO3?
What happens when HCl is added to Na2CO3?
Answer. Answer: Explanation: Well, HCl is an acid and it reacts with the metal carbonate Na2CO3 to give CO2 (carbon dioxide) , H2O and NaCl ( sodium chloride).
What does 10H2O signify Does it make Na2CO3?
Answer. As the formula for sodium carbonate (Na2Co3. 10H2O) Doesn’t meant that it is wet. It is just implies that the sodium carbonate is hydrated by water.
What is meant by water of crystallization give example?
Water of crystallization is the amount of water molecules which are present in one formula unit of salt. We can also say that the water molecules which form part of a structure of a crystal are called water of crystallization. They give the crystals their shape and crystal. Example : CuSO4.
What is crystallization give two examples?
(a) Water of crystallisation is the number of water molecules that combine chemically in definite molecular proportion, with the concerned salt in the crystalline state. (b)Two correct examples are: Copper sulphate, chemical formula – CuSO4.5H2O. Washing soda, chemical formula – Na2CO3.10H2O.
Does baking soda has water of crystallization?
1 Answer. B – Baking soda does not contain water of crystallization. The chemical formula of baking soda is NaHCO3. Its formula does not show any association with water molecules.
Does NaCl have water of crystallisation?
In sodium chloride, there is no water of crystallization, but it is in crystalline shape. It is a crystalline salt without water of crystallization. Actually NaCl dissolves in water completely and when it is vapourized, it doesn’t unite with any amount (molecules) of water, so it doesn’t have water of crystallization.
What are hydrated salts and water of crystallization?
The water molecules which form part of the structure of a crystal are called water of crystallisation. The salts which contain water of crystallisation are called hydrated salts. The water of crystallisation gives the crystals of the salts their shape and colour.
