Question

A.) Calculate the solubility in g/L of AgBr in pure water.

B.) Calculate the solubility in g/L of AgBr in 0.0018 M NaBr. (Enter answer in scientific notation.)

Answer #1

**Ksp of AgBr = 5.0*10^-13**

**molar mass of AgBr = 187.77 g/mol**

**A)**

**AgBr ßà Ag+ + Br-**

**
s s**

**Ksp = s^2**

**5.0*10^-13 = s^2**

**s = 7.071*10^-7 mol/L**

** = 7.071*10^-7*187.77 g/L**

** =1.335*10^-4 g/L**

**Answer: 1.335*10^-4 g/L**

**B)**

**Ksp = [Ag+] [Br-]**

**5.0*10^-13 = s*0.0018**

**s = 2.78 *10^-10 mol/L**

** = 2.78*10^-10*187.77 g/L**

** =5.22 *10^-8 g/L**

**Answer: 5.22 *10^-8 g/L**
