Adding Na2CO3 (sodium carbonate) during the purification of NaCl helps to remove impurities, particularly those that are soluble in water, such as certain metal ions. The carbonate ions can react with these impurities to form insoluble precipitates, which can then be separated from the NaCl solution. This process enhances the overall purity of the sodium chloride by selectively removing unwanted contaminants.

The chemical formula of potassium chloride is KCl.


How do you balance chemical equation fecl2 plus na2co3 yields nacl plus feco3?

To balance the chemical equation FeCl2 + Na2CO3 → 2NaCl + FeCO3, you would need to adjust the coefficients in front of each compound. Start by balancing the metal atoms, then balance the non-metal atoms, and finally balance the charges. In this case, the balanced equation is 2FeCl2 + 3Na2CO3 → 6NaCl + FeCO3.


What occurs when you add carbon dioxide to seawater?

Seawater is essentially NaCl + H2O. Adding CO2 will simply acidify the water, since CO2 + H2O ==> H2CO3 (carbonic acid). The NaCl can react to form Na2CO3 (sodium carbonate) and HCl, but all ions will be in solution, so there is no reaction, per se. Na^+ + Cl^- + 2H^+ + CO3^2- ==> no reaction


What is the formula mass of the compound formed between al3 plus and cl?

The formula mass of the compound formed between Al3+ and Cl- is determined by adding the atomic masses of aluminum (Al) and chlorine (Cl), considering the charges on the ions. The formula mass would be 133.34 g/mol.

How do you balance this equation Cl NaI NaCl I?

To balance the equation Cl₂ + 2NaI -> 2NaCl + I₂ you need to ensure that the number of each element is the same on both sides of the equation. In this case, you balance the equation by adding a coefficient of 2 in front of NaCl and I₂ to balance the number of atoms of Na, Cl, and I.

What do you do to not have a green pool while waiting to switch from cholorine to baquacil?

There really should not be too much of a problem when switching from CL to Baquacil. You just have to wait until the CL reading is down to zero and then start adding the products. The sun disepates the CL so quickly it should only take a couple days at most.


Does salt and water moke a solution?

Yes. Adding salt (NaCl) to water makes a homogenous solution of water molecules, Na+ ions and Cl- ions.

Which is more covalent H-Cl or Cl-Cl?

H-Cl is more covalent than Cl-Cl because the difference in electronegativity between hydrogen and chlorine is greater than that between two chlorine atoms, leading to a more polarized and covalent bond between H and Cl.
