Calculate the potassium ion (K+) concentration for a 0.899 M K₂CO3 solution.

Sagot :

Answer:

Concentration of 1.798 M of the potassium ion.

Explanation:

1st) It is necessary to write the dissociation equation of K2CO3:

[tex]K_2CO_3\rightarrow2K^++CO_3^{-2}[/tex]

2nd) In the dissociation equation of K2CO3, we can see that from 1 mole of K2CO3, 2 moles of potassium ion (K+) are formed, so from 0.899 M K2CO3 solution we will have:

2 x 0.899M = 1.798 M

a concentration of 1.798 M of the potassium ion.
