What is equivalent weight of KMnO4 in acidic basic and neutral medium?
Equivalent mass is the molecular mass divided by the number of electrons gained. The molecular mass of \[KMn{{O}_{4}}\] is 158.04g. So, the correct option is (d).
What is the equivalent mass of KMnO4 when it acts as oxidizing agent in acidic medium *?
Answer: Equivalent mass of in acidic and alkaline medium is 31.6 and 52.7 respectively.
What is the equivalent weight of potassium permanganate KMnO4 )?
potassium permanganate has a molar mass of 158.034(1) g mol−1, and reacts with five moles of electrons per mole of potassium permanganate, so its equivalent weight is 158.034(1) g mol−1/5 eq mol−1 = 31.6068(3) g eq−1.
How do you find the equivalent weight of KMnO4?
The Mn in KMnO4 exists in +7 state. In Acidic medium, This Mn +7 goes to Mn+2 state and hence there is a net gain of 5 electrons. Therefore,The Equivalent Weight = 158/5 = 31.6 grams.
How does KMnO4 equivalent weight change with medium?
In Acidic medium, This \[M{{n}^{+7}}\]goes to \[M{{n}^{+2}}\] state and hence there is a net gain of 5 electrons. Therefore, equivalent weight in acidic medium = 158/5 = 31.6 g.
What would be the gram equivalent weight of KMnO4 as an oxidizing agent in acidic solution?
So the n-factor of KMnO4 in acidic medium is 5. So the equivalent weight of the KMnO4 will be M/5 i.e. 158/5 = 31.6.
When KMnO4 having molecular mass M is used in an alkaline medium its equivalent weight will be?
i) The equivalent weight of KMnO4 in alkaline medium is 158.
What does KMnO4 give in basic medium?
Explanation. KMnO4 oxidised in acidic, basic as well as in neutral medium. Let us have a look at it. The oxidation state of the Mn atom in KMnO4 is +7.
What is the equivalent mass of KMnO4 in alkaline solution explain?
i) The equivalent weight of KMnO4 in alkaline medium is 158. ii) The number of electrons gained by one molecule of KMnO4 in the alkaline medium is 1. iii) In the alkaline medium, KMnO4 acts as a reducing agent.
What is the equivalent weight of KMnO4 in acidic medium molecular weight of KMnO4 158g?
