Question

In presence of a strong oxidising agent
As,S, is oxidised to arsenate and
sulphate. What is the n-factor of As, Sz.
1) 4 2) 18 3) 28 4) 24
​

Answer 1

The n-factor of As and S, In presence of a strong oxidising agent  is oxidised to form arsenate and  sulphate is 4. So, option (a) is the correct choice.

• N - factor can be defined in a number of ways for different chemicals, such as for acid n-factor is considered as the basicity, that is, number of replaceable positive hydrogen ions per molecule.
• So, in presence of storng oxidising agent, the number of  atom in arsenic and sulphur molecules that can be replaced is 4. So n factor is 4.
