White arsenic is produced by reducing arsenic in liquid sulfur dioxide; are there any requirements regarding the pH value for this reduction reaction?

@Chiharu Eiko needs to be resolved.
When reduced with sulfur dioxide, the medium must be acidic.
It can be reduced in strong acids; you talk to me about pH values, and I’ll tell you –0.2
It’s a negative value; the arsenic-containing solution of sulfuric acid at 200 grams per liter in our company is obtained by reducing sulfur dioxide
