SUMMARY This experiment involves argentometric titration .With help of indicator we observed the color change and we did the calculations according to our experiment results, and explained the possible sources of errors made during the experiment that caused us to repeat the same experiment for four times. As a result we determined the amount of chloride ion with a small error percentage according to the theoretical expectations. In the experiment we used burette, erlenmeyer flask, pipettes, K 2 CrO 4 (As indicator), AgNO 3 , NaCl solution.
