So, six moles of cationic charge is replaced by 2 moles of Na3PO4, thus each mole of Na3PO4 replaces 3 moles of cationic charge. Hence, n-factor of Na3PO4 in this reaction is 3.

Q. What is the smell of SO3?
Sulfur dioxide is a colorless gas with a pungent odor. Sulfur dioxide in the environment is the result of activities such as burning of coal and oil for electricity and heat. Specifically, the sulfur produced by these processes combines with the oxygen in the air.
Q. What is SO3 used for?
SO3 is also called sulfuric oxide and sulfuric anhydride. It is used in the production of sulfuric acid and other chemicals, and explosives. Sulfuric acid is a clear, colorless, oily liquid that is very corrosive. It is also called sulphine acid, battery acid, and hy drogen sulfate.
Q. Why is SO3 not added directly to water?
The correct answer of this question is option ‘c’, sulphur trioxide is not directly dissolved in water to form sulphuric acid because it results in the formation of dense fog of sulphuric acid which is difficult to condense.
Q. How do you find the N factor of a salt?
In reactions like this where there’s no change in oxidation number, the n-factor will always be the net positive charge in 1 molecule of that compound, in this case since there are 3 Na ions in sodium phosphate, the n-factor=3×1=3.
Q. What is the N factor of kmno4 in acidic medium?
n-factor is defined as the number of H + ions replaced by 1 mole of acid in a reaction. In neutral medium KMnO4 forms MnO2 (+7 to +4) i.e. it gains 3 electrons. So, n-factor= 3….Thank you.

Q. What is n factor of K2Cr2o7?
Answered 3 years ago. In basic medium,the reaction of potassium dichromate is. K2Cr2o7+2NaoH=K2Cro4+Na2Cro4+H2o. In this reaction the oxidation state of Cr change+6 to+3 so that the n-factor is 3.
Q. Is K2Cr2O7 an acid or base?
A potassium salt that is the dipotassium salt of dichromic acid. Potassium dichromate, K2Cr2O7, is a common inorganic chemical reagent, most commonly used as an oxidizing agent in various laboratory and industrial applications.
Q. What is n factor of potassium dichromate?
Potassium dichromate in an acidic medium is a strong oxidizer. It means it gains electrons during redox reaction. There is overall gain of 6 electrons. That means n-factor for this reaction is 6.
Q. How do you find the factor of potassium dichromate?
The equation for potassium dichromate in basic medium follows:
- Net ionic equation follows:
- Oxidation state of Chromium in reactant side:
- Oxidation state of Chromium at product side:
- Therefore, the n-factor for this atom will be (6 – 3) = 3.
Q. What is equivalent weight of K2Cr2O7?
49g/
Q. What Colour is K2Cr2O7?
red-orange
Q. What is the main cause of color of K2Cr2O7?
KMno4 and K2Cr2O7 are colored because of the charge transfer spectra. In both of these compounds andelectron from a oxygen lone pair character orbital is transferred. This transfer helps in giving color to the compounds.
Q. What is the hybridization of K2Cr2O7?
Now each Cr atom accept electrons from oxide ions in their empty d orbitals, forming dichromate ion. This has been given in the following picture. So the hybridization is sd3.
