ABSTRACT

Complexometric method is a titration method with the principle formed a complex

compound between ligan (titrant) with metal ion (analyt). The purpose of this

practice that to know consentration a metal (ZnO) from the sample. There was 4

kinds of complexometric titration that!s direct titration back titration indirect

titration and substitution titration. "n this practice used direct titration principle

where metal ion reacted with #$T% (ligan) directly without precipation process.

"ndicator that was used in this practice was #riochrome &lack'T that the solution

changed colour from iolet into blue. #$T% was standardiation with standard

solution Zn*O4. Concentration of #$T% after standardiation process was ++,-,

. Concentration of ZnO was /0--01.
