We use sulphuric acid in this titration with KMnO4. The solution which contains MnO4- ion in it is purple in color. While the solution containing Mn+2ions is colorless. Thus, potassium permanganate when reacts with a reducing agent it works as a self-indicator also. In the experiment, oxa...
Titer of 1/5 KMnO4 0.1 mol/L / M527 Method for the standardization of potassium permanganate. With minor changes the method can be used for the titer determination of many other oxidizing agents. Titer of Na2S2O3 0.1 mol/L / M526 Method for the standardization of 0.1 mol/L sodium thio...

Titration of HCl with NaOH can be done by potentiometric titration. This concentration of a given acid/base is determined by using a standard solution. Redox Titration Potentiometric titration was first used for redox titration by Crotogino. He titrated halide ions with KMnO4using a platinum electro...
(eq wt) : • eq wt in a neutralization reaction : weight which either contributes or reacts with one gram hydrogen ion. - NaOH, HCl each has only a single reactive hydrogen ion or hydroxide ion eq wt = MW - H 2 SO 4 : strong acid ให้ 2 H + ; H 2 SO 4 : 0.5 M...
