Seawater, which covers the majority of the earth, is composed primarily of molecules of H2O and equal numbers of Na+ ions and Cl- ions. Suppose we have a thoroughly mixed solution (containing these species only) at 25°C. How many components and how many phases are in such a system?

Respuesta :

Explanation:

It is given that the given system contains [tex]H_{2}O[/tex], [tex]Na^{+}[/tex], and [tex]Cl^{+}[/tex].

Therefore, formula for number of components is given as follows.

              C = n - E

where,   E = no. of independent equation relating the concentration of species

             n = number of species involved

Now, put the given values into the above formula as follows.

            C = n - E

               = 3 - 1

               = 2

Since, NaCl when dissolves in water leads to the formation of a homogeneous mixture. Hence, then phase will be equal to 1.

thus, we can conclude that in the given system there are 2 components present in 1 phase.
