I just used this test for the first time. The first drop of Silver Nitrate caused a precipitate that I was not expecting. As I continued to titrate, the sample turned almost milky in color, and on the 17th drop it turned a reddish milky color so I stopped.

Is this normal? 17 x 200ppm = 3,400 ppm which is about right, but I am not sure the test was good. Anyone with experience with this test?
