Options
- Ato increase the concentration of OH ⁻ ions
- Bto precipitate the radicals of group IV and V
- Cto suppress the dissociation of NH ₄ OH
- Dto introduce Cl ⁻ ions
Correct answer
C. to suppress the dissociation of NH ₄ OH
Step-by-step solution
In the analysis of III group basic radicals of salts, the purpose of adding NH ₄ Cl (s) to NH ₄ OH is, to suppress the dissociation of NH ₄ OH due to the common ion effect.
