How many grams of Mg is required to completely reduce 100ml, 0.1M NO3- solution using the following reaction
NO3-+MgMg2++NH3

  1. A 0.96
  2. B 0.62
  3. C 0.24
  4. D 0.75
Verified Solution

Answer & Solution

Correct Answer

(A) 0.96

Step-by-step Solution

Detailed explanation

Given reaction NO3-+5+Mg0⟶Mg2++2+N-3H3 In this redox reaction oxidation state of N is changing from +5 to -3. So, n-factor for the NO3- will be 8. And for the Mg it will be 2. Now according to Law of equivalent, Number of equivalent of both should be equal.…
