MCQ
In Bredig's Arc method, the stabilizer used is:
- A$\ce{Ca(OH)_2}$
- B$\text{CaO}$
- ✓$\text{KOH}$
- D$\ce{K_2O}$
✓
Answer
Correct option: C.
$\text{KOH}$
Bredig's arc method consists of both dispersion and condensation. An arc is struck between electrodes, under the surface of water containing stabilising agents such as $\text{KOH}.$ The intense heat of the arc vaporizes some of the metal which then condenses under cold water.
