I have a lab report and I need help on it.


1) In this experiment, what evidence do you have that indicates all AgNO3 reacted? Does the amount ofNaCl that is added need to be known precisely? Why or why not? I will also upload the needed files

2) Suppose one was doing this experiment in the real world and the stockroom ran out of NaCl solutions.Which other solutions of similar concentration could be used in place of NaCl(aq)? KF(aq), KNO3(aq),NaClO4(aq), KBr(aq), K(C2H3O2)(aq) (potassium acetate) Hint: Check out Solubility Rules of IonicCompounds in Water.

3) In a similar experiment, concentration of Pb(NO3)2 is determined by adding 0.100 M NaBr to 55.50 mLof Pb(NO3)2 solution with unknown concentration. It is found that maximum amount of precipitatethat can form is 1.215 g.a) Write out a balanced molecular equation for this precipitation reaction.b) What is the original concentration of Pb(NO3)2 in the unknown solution.
