In cases of particular elements during reactions we see the change is their individual oxidation states.But if we have to calculate the equivalent weight of a species in a particular reaction,we have to find out the n factor for that particular species in the reaction.It is basically the overall exchange of electrons of a species per mole of that species in the reaction.
And 1 thing more,n factor can never be calculated for individual atoms.
For example:if we have to find out the equivalent weight of Fe2S3 in the reaction
Fe2S3 --> FeSO4 + SO2
First v balance the equation which gives
Fe2S3 + 502-->2FeSO4 +SO2
Then v find out the oxiadation states of S in d differsnt compounds cos v c that S is the only common element in all.In Fe2S3 The ox.state of s is -2.In FeS04 it's +6 n in SO2 it's +4.
So we c the net exchange of electrons per mole of Fe2S3 in d reaction is
2*(+6-(-2))+(4-(-2)) = (2*8)+6 =22
Therefore the n factor of Fe2S3 is 22.
So its equivalent weight will be Molecular weight/22.

How to prepare 0.2N HCl solution?
0.2 N HCl solution means 0.2 equivalents of HCl dissolved in 1 litre of water. Normality = Molarity x n-factor => Molarity =Normality/n-factor=0.2/1=0.2 M 0.2 moles should be present in 1 litre of solution. 0.2moles =0.2 x 36.5 = 7.3 grams of HCl =>Dissolve 7.3 grams of HCl in 1 litre if water to get a 0.2N solution.
Is concentration typically given with the volume of solvent or the volume of solution?
The concentration of a solution is typically given in terms of the volume of solution, in liters.
What metal solution is called a n?
A solution of two or more metals is called an alloy.
What is the n factor of boric acid?
1
How much water is needed to dilute 10 L of 3.0 N HCl solution to 0.2 N HCl solution?
Add 5 litres water.
What is the factor of n squared plus 2n?
Obviously, both terms have the common factor "n". You get the other factor by dividing both terms by n. The result is "n + 2".
How many sides will a 40 diagonals have?
If the polygon has n sides, it has n*(n - 3)/2 diagonals So, n(n - 3)/2 = 40 or n(n - 3)= 80 for which there is no solution. The question has no answer in terms of plane geometry.

What is the solution to the equation n 12 17?
Without an equality sign and not knowing the plus or minus values of the given terms it can't be considered to be an equation and so therefore there is no solution.
Can you simplify 17 over 280?
No, because 17 is not a factor of 280. 17/280 is already i n lowest terms.
What is the nth term of ap if sum of n terms of ap is 2n plus 1?
There is no solution to the question as asked. If the sum of n terms is 2n+1 then the sum of n+1 terms, using the same formula, is 2*(n+1)+1 = 2n+2+1 = 2n+3 So the (n+1)th term is sum to n+1 minus sum to n = (2n+3) - (2n+1) = 2 So each term is 2. But if each term is 2, then the sum of n terms must be even. The sum is clearly odd - which leads to a contradiction.
How do you solve by factoring if you only have something like n squared plus 5n equals 0?
n^2 + 5n = 0Where there is no constant term, then there is one monomial and one binomial factors. In this case the monomial is n and the binomial is (n + 5) So n*(n + 5) = 0 which leads to the solutions n = 0 or n = 5.
What is the solution set of 18 - 3n plus 2 equals n plus 20 - 4n?
18 - 3n + 2 = n + 20 - 4n gather terms together on both sides of equation - 3n + 20 = - 3n + 20 0 = 0 =============no true solution here Actually, it's an infinite number, not "no solution" because it can also be done to end with n=n. I realize you didn't strictly say "no solution" but that's what it sounds like, so I'm just clarifying. -3n+20=-3n+20 -3n=-3n n=n
What is Solution of the equation?
In algebraic terms, the solution is the answer to equation.
Solve the equation 28 -4 n plus 15?
Without an equality sign the given terms can't be considered to be an equation and so therefore there is no solution.
What means n terms in math?
N terms means any number on to infinity.
Can you factor polynomial 8nĀ²-36n plus 40?
Divide all the terms by 4:- 2n2-9n+10 = (2n-5)(n-2) when factored
