# Problem: Describe how you would prepare each of the following aqueous solutions, starting with solid KBr.a 0.160 M solution of KBr that contains just enough KBr to precipitate 17.0 g of AgBr from a solution containing 0.480 mol of AgNO3

###### FREE Expert Solution

KBr reacts with AgNO3 in a double displacement reaction to produce AgBr and KNO3. In this reaction Ag+ from AgNO3 will react with Br- from KBr to produce AgBr, which precipitates from the solution.

Recall that silver halides are insoluble. We will solve this problem through these steps:

• Find mass of KBr through
• Converting mass of AgBr to moles
• Find moles of KBr from moles of AgBr using the mole ratio as in the above equation
• Find mass of KBr
• Find the volume of 0.160 M KBr solution that contains the mass of KBr just calculated
