Pre-lab math exercises

3. Pre-lab math exercises: 

 

a) A silver nitrate (AgNO3) solution is 0.150 M. 100.0 mL of a diluted silver nitrate solution is prepared using 10.0 mL of the more concentrated solution (which is then diluted with distilled water to 100.0 mL). Use the dilution equation to find the molarity of silver nitrate in the diluted solution. 

 

b) Silver ion (Ag+) forms a complex with ammonia (NH3); the formula of the silver ammine complex is [AgNH3]+. Write the equilibrium reaction for the formation of the complex from the ions. 

 

c) Silver ammine ([AgNH3]+) has an equilibrium constant value of 1.7x103. If 0.015 M silver ion is mixed with 0.100 M ammonia, what are the concentrations of reactants and products at equilibrium? (Hint: use an ICE table) 

 

4. Flowchart the procedures (on new pages). Don’t forget to watch for places to take data and make observatio
