Solución
To solve for the solubility of CuBr in pure water and in a
solution, we need to follow these steps:
-
Find the
value for CuBr: This value is typically provided in the data tab. Let’s denote it as . -
Set up the solubility equilibrium expression:The solubility product constant expression is:
-
Calculate the solubility in pure water:
Letbe the solubility of CuBr in mol/L. Then: Therefore, we can findby rearranging: -
Calculate the solubility in
:
The dissociation of CoBr₂ gives:The concentration of Br⁻ from CoBr₂ is. The equilibrium expression becomes:Thus:Rearranging gives: -
Calculate both solubilities and round to 2 significant digits.
Now, please provide the
value for CuBr so I can perform the calculations.

Solubility in Pure Water: The dissociation of CuBr in water can be written as:The
expression is: If the solubility of CuBr in pure water is, then and , so: Solving forgives: -
Solubility in
: CoBr dissociates into Co and 2Br : Therefore, the concentration of Brfrom the CoBr solution is 0.0220 M. Let be the solubility of CuBr in this solution. The total concentration of Br becomes . The equilibrium expression modifies to: Solving this quadratic equation will give the adjusted solubility.
Make sure to check your
value from ALEKS Data, plug it into the calculations above, and solve for both solubilities, rounding to two significant digits!
