How do you calculate HCl factor?

1 Answer

  1. NaCl(s)→Na+(aq)+Cl-(aq);i=2. One formula unit of NaCl will form two particles in solution, an Na+ ion and a Cl- ion.
  2. CaCl2(s)→Ca2+(aq)+2Cl-(aq);i=3. One formula unit of CaCl2 will form three particles in solution, a Ca2+ ion and two Cl- ions.
  3. Fe2(SO4)3(s)→2Fe3+(aq)+3SO2-4(aq);i=5. For a weak electrolyte.

How do you find the N factor of a reactant?

To calculate n-factor of a salt of such type, we take one mole of the reactant and find the number of mole of the element whose oxidation state is changing. This is multiplied with the oxidation state of the element in the reactant, which gives us the total oxidation state of the element in the reactant.

What is n factor of K2Cr2O7 in basic and neutral medium?

Hence the n-factor is 6.

How do you find N in a chemical reaction?

General rule: Find the number of electrons in each balanced HALF-reaction. If they match, that is n (First example). If they don’t match, take the lowest common multiple, and that is n (Second/third examples).

What is the reaction between HCl and K2Cr2O7?

K2Cr2O7 is an oxidising agent. It needs reducing agent to react. HCl is just a acid and not a reducing agent. Therefore this reaction doesn’t take place in absence of reducing agent. Why do we use HCL in KMnO4 + 8HCl + FeSO4 → KCl + MnSO4 + 4H2O + FeCl3 + 2Cl2?

What is the n-factor of CR in this reaction?

In this reaction the oxidation state of Cr change+6 to+3 so that the n-factor is 3. In this reaction theOxidation number of Cr changes from+6 to +6.but in right side there is 2 chromium ,so that the oxidation no.change from +6 to 2* (+6). Hence the n-factor is 6.

What is the n-factor of HCl+HCl reaction?

In this reaction, For hydrogen there is no change in the oxidation number, but for Chlorine changes from minus one to zero. So, number of electrons exchanged is one per Chlorine atom. And one unit formula of HCl contains one Chlorine. So, total exchange is one. Hence, n-factor is one.

What is the equivalent mass of HCl oxidised to Cl2?

In the given equation, HCl is oxidised to Cl2 Change in oxidation number = 0- (-1) = 1 n factor= 6 / 14 Molecular mass of HCl is = 36.5 Equivalent mass = (Molecular mass of HCl)/ (n factor) = 36.5/ (6/14) = 85.1 Hence 85.1 is the equivalent mass of HCl.
