The solubility of CuBr in water at 25°C is measured to be 0.010gL . Use this information to calculate Ksp for CuBr . Round your answer to 2 significant digits.

Ksp = 4.86 *10^-9

Explanation:

Step 1: Data given

The solubility of CuBr in water at 25°C is measured to be 0.010 g/L

Temperature = 25.0 °C

Step 2: The balanced equation

CuBr ⇔ Cu+(aq) + Br-(aq)

Step 3: Convert g/L to mol /L

0.010 g/L / / 143.45 g/mol = 6.97 * 10^-5 mol/L

Step 4: Define Ksp

Ksp = [Cu+][Br-]

There is a 1:1 ratio between CuBr and Cu+  and Br¯. T

This means, when 6.97 *10^-5 mol/L  of CuBr dissolves, it produces 6.97 *10^-5 mole per liter of Cu+ and 6.97 *10^-5 mole per liter of Br¯ in solution.

Step 5: Calculate Ksp

Ksp = [Cu+][Br-]

Ksp = [6.97*10^-5 M][6.97*10^-5 M]

Ksp = 4.86 *10^-9

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
