How do you find the equivalent weight of potassium permanganate?
The molar mass of potassium permanganate is 158 g/mol. To find the equivalent mass, divide that molar mass by the mols of electrons taken in its half reaction. That would be five. 158/5 = 31.6 grams/equivalent.
How do you calculate gram equivalent weight?
Gram equivalent weight is equal to mass in grams numerically equal to Equivalent Weight. To calculate the Gram Equivalent Weight, we use the formula Eq = MW / n.
What cr2o7 2?
Description. Dichromate(2-) is a divalent inorganic anion obtained by removal of both protons from dichromic acid. It is a chromium oxoanion and a divalent inorganic anion. It is a conjugate base of a hydrogen dichromate.
What is the equivalent weight of K2Cr2O7?
Equivalent weight of K2Cr2O7 is 49 g/mol. Here, 6 e- participate in the reaction, hence chemical equivalent is 6. Equivalent weight of K2Cr2O7 in acidic medium is 49 g/mol.
What foods contain potassium dichromate?
Load Up on Dark Leafy Greens like Spinach and Bok Choy. Some of the best sources of potassium are dark leafy greens such as spinach, which when cooked has more than 800 mg of potassium per cup; bok choy, which contains around 600 mg per cup when boiled, and Swiss chard, which has almost 1,000 mg per cooked cup.
What is the molar mass of potassium chromate?
Formula and structure: The chemical formula for potassium dichromate is K2Cr2O7 and its molar mass is 294.185 g/mol.
What is the charge of dichromate?
Its overall charge is -2. Dichromate is similar, but it contains two chromium atoms and seven oxide atoms (therefore, Cr 2O 7). Chromate and dichromate are strongly oxidizing in acidic conditions, but weakly oxidizing in basic conditions.
What contains potassium dichromate?
Potassium dichromate is an industrial chemical found in leather, dyes, paints, glues, shoe polishes, floor waxes, detergents and wood preservatives. According to the Material Safety Data Sheet, or MSDS, potassium dichromate is hazardous.
