What is the equivalent weight of potassium chromate What is the equivalent weight of KMnO4 in neutral medium?
The equivalent weight of potassium chromate (K2CrO4) is equal to its molar mass divided by the change in oxidation number of the central atom upon reduction. For KMnO4 in a neutral medium, the equivalent weight is calculated similarly, taking into account the change in oxidation number of manganese from +7 to +2 upon reduction.
What is the equivalent weight of potassium permanganate in alkaline medium?
The equivalent weight of potassium permanganate in alkaline medium is 31.6 g/mol. This value takes into account the reduction of permanganate ions to manganese dioxide in alkaline conditions, resulting in a different equivalent weight compared to acidic conditions.
Equivalent weight of succinic acid?
The equivalent weight of succinic acid is the molecular weight divided by the number of acidic hydrogen atoms. Since succinic acid has two acidic hydrogen atoms, its equivalent weight is molecular weight/2. The molecular weight of succinic acid is 118 g/mol, so its equivalent weight is 118/2 = 59 g/mol.
What is the equivalent weight of phosphoric acid?
The equivalent weight of phosphoric acid (H3PO4) is 98 g/mol. This is calculated by dividing the molecular weight by the number of acidic protons that can be donated during a reaction, which in this case is 3.
What is the gram-equivalent weight of sulfuric acid?
The gram equivalent weight of sulfuric acid (H2SO4) is 98 g/mol, as it has two acidic hydrogen ions that can be replaced in a neutralization reaction.

What is the Equivalent weight of KMnO4 in different medium?
The oxidation state of 'Mn' in KMnO4 is +7 after reaction as oxidizing agent 'Mn; becomes +2 so change in oxidation number is '5' the formula mass divided by change in oxidation number is equal to equivalent mass or weight, 158/5 = 31.7
Equivalent weight of succinic acid?
The equivalent weight of succinic acid is the molecular weight divided by the number of acidic hydrogen atoms. Since succinic acid has two acidic hydrogen atoms, its equivalent weight is molecular weight/2. The molecular weight of succinic acid is 118 g/mol, so its equivalent weight is 118/2 = 59 g/mol.
Gram equivalent weight of EDTA?
The gram equivalent weight of EDTA (Ethylenediaminetetraacetic acid) is calculated by dividing its molar mass by the number of acidic hydrogen ions it can donate. Since EDTA can donate 4 acidic hydrogen ions, its gram equivalent weight is typically 372 g/mol divided by 4, which equals 93 g/equivalent.
What weights 1kg?
A 1kg weight would be equivalent to approximately 2.2 pounds, or about the weight of a medium-sized pineapple.
What is the equivalent weight of phosphoric acid?
The equivalent weight of phosphoric acid (H3PO4) is 98 g/mol. This is calculated by dividing the molecular weight by the number of acidic protons that can be donated during a reaction, which in this case is 3.

How can calculate equivalent weight of calcium carbonate?
The equivalent weight of calcium carbonate can be calculated by dividing its molecular weight by the number of acidic hydrogen ions that it can donate in a reaction. In the case of calcium carbonate, it can donate two moles of hydrogen ions, so the equivalent weight would be its molecular weight divided by 2.
What is equivalent weight of disodium EDTA?
Well, honey, the equivalent weight of disodium EDTA is approximately 292 grams per mole. It's just a fancy way of saying how much of the compound is needed to react with one equivalent of a given reactant. So, if you're looking to do some chemistry magic, there's your answer.
How to prepare a 0.2N KMnO4 solution?
Formula weight of KMnO4 is 158.04. The equivalent weight depends on the reaction involved. In acidic media it is (formula weight) /5, in neutral although this is more difficult to control it is the formula weight. Knowing which type it is usually acidic as it is easier, you will need 158.04/5 X 0.2 = 6.32g. Sulfuric acid is usually added in the titration to ensure the correct oxidation reaction is carried out. Also note KMnO4 is not considered a primary standard so you should really filter the solution to remove any MnO2 caused by oxidation of organic impurites in the water you are using, and standardise the solution by titration against say oxalic acid.
