Four solution are prepared and mixed together:
Start with 100.0ml of 0.100M BaCl2.
Add 50.0ml of 0.100M AgNO3.
Add 50.0ml of 0.100M H2So4.
Add 250.0ml of 0.100M NH4.
Write an equation for any reaction that occurs after each step and calculate the concentration of Ba,CL,NO3,NH4 in the final solution assuming that all reaction go to completion

This is a work horse of a problem. I'll start the first one.
2AgNO3 + BaCl2 ==> 2AgCl + Ba(NO3)2
(Ba^2+) = 0.1 M x (100/450) = ?
(NO3^) = 0.1 M x (50/450) = ?
etc.
