It is a purplish-black crystalline salt, which dissolves in water as K + and MnO − 4 ions to give an intensely pink to purple solution. Potassium permanganate is widely used in the chemical industry and laboratories as a strong oxidizing agent , and also as a medication for dermatitis , for cleaning wounds , and general disinfection .
First step is to plot the absorbance(A) values of standard solution against molar concentrations (c) of the known solution. Then the best straight line is plotted, passing through the origin. The experimental points are plotted as per Beer’s law: A= E*c*l where E= molar extinction coefficient and l= optical path length usually 1 cm.
The reaction is considered Markovnikov as it results in water addition with same regiospecificity as a direct hydration reaction. Alkene hydroboration-oxidation: Stereospecific: Can only be syn addition – hydrogen and hydroxyl (-OH) are added to the same face. The reaction is anti-Markovnikov. Hydroxyl attaches to the less substituted carbon.
Authorities have identified the woman who burned to death after she was set on fire inside a New York City subway train as 57-year-old Debrina Kawam.
I cracked up when he asked if she liked it, and she looked at him like he was crazy! ... Commenters also got a kick out of the Corgi's reaction. @PrarieRose pointed out, "Awwww the look in her ...
The graph for these equations is a sigmoid curve (specifically a logistic function), which is typical for autocatalytic reactions: these chemical reactions proceed slowly at the start (the induction period) because there is little catalyst present, the rate of reaction increases progressively as the reaction proceeds as the amount of catalyst ...

Knowing the analytical concentrations of reactants initially in the reaction vessel and in the burette, all analytical concentrations can be derived as a function of the volume (or mass) of titrant added. The equilibrium constants may be derived by best-fitting of the experimental data with a chemical model of the equilibrium system.
