Answer

To find the solubility of CuBr in pure water and in a solution, follow these steps:
  1. Find for CuBr from the ALEKS Data tab.
  2. Calculate solubility in pure water:
    Round to 2 significant digits.
  3. Calculate solubility in :
    Round to 2 significant digits.
Provide the value to get the exact solubility.

Solution

To calculate the solubility of CuBr in pure water and in a solution, we need to follow these steps:
  1. Find the value for CuBr: This value is typically provided in the data tab. Let’s denote it as .
  2. Set up the solubility equilibrium:
    • The dissolution of CuBr can be represented as:
    • The solubility product expression is:
  3. Calculate the solubility in pure water:
    • Let be the solubility of CuBr in mol/L. Then:
    • Solve for :
  4. Calculate the solubility in :
    • In this case, the concentration of Br ions from CoBr will affect the solubility of CuBr. The equilibrium will be:
    • Let be the solubility of CuBr in this solution. Then:
    • Solve for :
Now, please provide the value for CuBr so we can proceed with the calculations.

Bonus Knowledge

To find the solubility of CuBr in pure water and in a solution, we need the solubility product constant ( ) value for CuBr, which can typically be found in data references. Assuming the is provided, let’s break it down step by step.
  1. Solubility in Pure Water:
    The dissolution of CuBr can be represented by the equation:
    If the solubility of CuBr in water is mol/L, then:
    Thus,
    Substitute value to find in mol/L, then convert it to g/L using the molar mass of CuBr (approximately 143.45 g/mol).
  2. Solubility in Solution:
    In the presence of , which dissociates to give and , the concentration of increases. For , the concentration of contributing to the equilibrium will be . Therefore:
    Rearranging gives:
    This concentration of Cu will be your solubility in the presence of the .
Now, simply plug in the value you’ve found and do the calculations! After solving, round your results to two significant digits for both solubility in pure water and the solution.
