Oxidation Reduction Titrations* ... Photometric Titrations* Photometric titrations utilize a color change to determine the endpoint of the titration. This either occurs naturally between the titrant and the sample, or through a ...
In analytical chemistry, potentiometric titration is a technique similar to direct titration of a redox reaction. It is a useful means of characterizing an acid. No indicator is used; instead the electric potential is measured across the analyte, typically an electrolyte solution. To do this, two electrodes are used, an indicator electrode (the glass electrode and metal ion indicator electrode) and a referenc… WebAbsorbance (A) คือ ค าดูดกลืนแสง เป นตัวเลขท ี่ใช บอกระด ับการด ูดกลืนแสงของสารละลาย โดยคํานวณได จากสูตร b Incident Light [ Io] Transmitted Light [ Is]
