Perché il sale non si scioglie nell'acqua?

Perché il sale non si scioglie nell'acqua?

Quando un solvente (acqua) ha raggiunto una quantità massima di soluto (sale) che non si scioglie più, si dice che la soluzione è satura.

How do you separate NaCl and CaCO3?

Let the water of the NaCl solution evaporate and you have separated NaCl and CaCO3. Sodium chloride is soluble in water while calcium carbonate is not. Add the mixture to water, filter out the undissolved calcium carbonate then boil off the water to recover your sodium chloride.

What is the reaction between calcium chloride and Na2CO3?

There is a formula to mix calcium chloride. Based on that formula, you can catch the reaction, such as: CaCl2 (aq) + Na2CO3 (aq) → CaCO3 (s) + 2NaCl (aq) First, you should write about the formula of those compounds. There are CaCl2 for calcium chloride and Na2CO3 for sodium carbonate. You will get a solid calcium carbonate and it is precipitated.

How do you remove NaCl from a mixture?

Stir water into the mixture and dissolve the NaCl, then pour off the solution and evaporate it to recover the separated NaCl. Dissolve it in water.

What is the formula for calcium chloride and sodium carbonate precipitate?

First, you should write about the formula of those compounds. There are CaCl2 for calcium chloride and Na2CO3 for sodium carbonate. You will get a solid calcium carbonate and it is precipitated.
