Question

In Bredig's Arc method,the stabilizer used is:

• A. $Ca(OH{)}_2$
• B. $CaO$
• C. $KOH$
• D. $K_{2}O$

Answer 1

Answer: (C)

$KOH$

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 $KOH$. The intense heat of the arc vaporizes some of the metal which then condenses under cold water.
