science chemistry# What is the N factor of na2co3?

Last Updated: 15th June, 2021

**N factor**will be 2. For a salt it is calculatedby the charge present on the electropositive cation here itssodium.

**Na2Co3 N factor**is 2.

Similarly, it is asked, what is the N factor of nahco3?

**n factor** for acids is its basicity, ie, number ofreplaceable hydrogen ion per molecule. For exampleg HCl has **nfactor** 1 **n** H2SO4 has 2 H3PO3 has **n factor** 2because when H3PO3 dissociates to form H+ and HPO3^-2. Same waysfor bases its **n factor** is its acidity or no of replaceableOH ions per molecule.

Subsequently, question is, how do you calculate the N factor of salt? To **calculate n**-**factor** of a **salt** of suchtype, we take one mole of the reactant and **find** the numberof mole of the element whose oxidation state is changing.

**For example,**

- n-factor of NaOH = 1.
- n-factor of Zn(OH)
_{2}= 1 or 2. - n factor of Ca(OH)
_{2}= 1 or 2. - n factor of AI(OH)
_{3}= 1 or 2 or 3. - n factor of NH
_{4}(OH) = 1.

Then, what is the N factor of N 8203?

The **n**-**factor** for is 2 whereas the**n**-**factor** for is 1. The **n factor** is the numberof H ions that can be replaced in the chemical compound. Whereasfor salt the **n**-**factor** is determined by the number ofpositive or negative ions that is present in the salt.

What is the Valency of Na2CO3?

Na(+) has a “**valency**” of +1 andCO3(2-) has a “**valency**” of -2, so the compoundis Na2(++) + CO3(2-) = **Na2CO3** which has no electricalcharge.
