In the detection of III group basic radicals NH ₄ OH is added after NH ₄ Cl to
Options
- Aincrease in the ionisation of NH ₄ OH
- Bincrease in the ionisation of salt solution
- Cdecrease in the jonisation of salt solution
- Ddecrease in the ionisation of NH ₄ OH
Correct answer
D. decrease in the ionisation of NH ₄ OH
Step-by-step solution
In the detection of III group, basic radicals NH ₄ OH is added after NH ₄ Cl to decrease the ionisation of NH ₄ OII due to common ion effect.
