Basic because a pH greater than 7 is basic
Answer:
Pure water has an acidity of about 7 on the pH scale. -is a chemical property of pure water. Pure water has an acidity of about 7 on the pH scale
Answer:
NaCl.
Explanation:
In the solution, ZnSe ionizes to
and
. Following reaction represents the ionization of ZnSe in solution -
⇄ ![Zn^2^+ + Se^2^-](https://tex.z-dn.net/?f=Zn%5E2%5E%2B%20%2B%20Se%5E2%5E-)
As we want to increase the solubility of ZnSe, we must decrease the concentration of dissociated ions so that the reaction continues to forward direction.
If we add NaCl to this solution, then we have
and
in the solution which will be formed by the ionization of NaCl.
Now,
in the solution will react with two
ions to form
as follows -
⇄ ![ZnCl_2](https://tex.z-dn.net/?f=ZnCl_2)
Due to this reaction the concentration of
will decrease in the solution and more ZnSe can be soluble in the solution.
