What is the purpose of adding sodium carbonate to the mixture?
Sodium carbonate is often added to a mixture to raise the pH level and increase the effectiveness of certain chemical reactions. It can also act as a buffering agent to help maintain a stable pH environment. Furthermore, sodium carbonate can be used to precipitate certain ions or compounds from solution.
How is anhydrous sodium carbonate converted to pure hydrated sodium carbonate?
Anhydrous sodium carbonate can be converted to hydrated sodium carbonate by simply adding water. When anhydrous sodium carbonate reacts with water, it forms hydrated sodium carbonate through a hydration reaction where water molecules are incorporated into the crystal structure, resulting in a hydrated form of the compound.
How could you separate nickel carbonate from sodium carbonate?
One way to separate nickel carbonate from sodium carbonate is by utilizing differences in solubility. Nickel carbonate is insoluble in water, while sodium carbonate is soluble. By adding water to the mixture and filtering, the insoluble nickel carbonate can be separated from the soluble sodium carbonate.
Is adding calcium chloride to sodium carbonate a physical change or a chemical change?
Adding calcium chloride to sodium carbonate would be a chemical change because it results in the formation of new substances (calcium carbonate and sodium chloride) with different chemical properties than the original reactants.
How long do you have to wait to get in the pool after adding sodium hydrogen bi carbonate?
You should wait about 6 to 8 hours before getting into the pool after adding sodium hydrogen carbonate. This will allow time for the chemical to dissolve and mix thoroughly in the water, ensuring that it is safe for swimming.
Why addition of sodium carbonate required in method esterification?
Strong base is added to neutralize the strong acid (H2SO4).

Why do you boil the solution after adding hydrochloric acid to a hydrated sodium carbonate?
to disolve quicker
What the purpose of adding sodium chloride during hard soap preparation?
Adding sodium chloride soap is precipitated.
What was the purpose of putting a salt in a mummy?
To suck the water out of the body to prepare for the after life; sodium carbonate is used, not sodium chloride.
How long do you have to wait to get in the pool after adding sodium hydrogen bi carbonate?
You should wait about 6 to 8 hours before getting into the pool after adding sodium hydrogen carbonate. This will allow time for the chemical to dissolve and mix thoroughly in the water, ensuring that it is safe for swimming.
Why adding sodium hydrogen carbonate to the water might help aquatic plants to grow?
It supports its grow
Chemical formula of sodium carbonate?
Sodium carbonate is Na2CO3(the more familiar compound, baking soda, is sodium bicarbonate, NaHCO3)
How can we make a solution of sodium carbonate?
Take water in a beaker. Add sodium carbonate to it and stir till sodium carbonate dissolves. However for scientific or any practical purpose, take a fixed weight of sodium carbonate and dissolve in a definite volume of water and calculate the concentration in terms of molarity or weight per volume etc.
