Abstract

Experimentally chloride determination is performed, with the Mohr method; which he argues that from the titration of silver nitrate (AgNO3) chloride ion precipitates, and you can see their point of equivalence by potassium dichromate indicator. In addition, the hardness test is also performed, for which EDTA was used as the standard and the indicator is black of diocromo. Finally determining purity phenolphthalein indicator as HCl and is performed; thus aim is to identify each in the wastewater sample and then perform calculations each.
