Question

Write the Ksp expression for the sparingly soluble compound cobalt(II) sulfide, CoS. If either the numerator or denominator is 1, please enter 1.

Answer 1

`Ksp=([Co^(2+)][S^(2-)])/(1)`

Step-by-step explanation:

Hello there!

In this case, according to the given information, it turns out firstly necessary to write the chemical equation for this reaction as shown below:

`CoS(s)\rightleftharpoons Co^(2+)(aq)+S^(2-)(aq)`

Thus, since solids are not included in equilibrium expressions, we can set this one up as follows:

`Ksp=([Co^(2+)][S^(2-)])/(1)`
