Question

Which of the following non metals are used as an electrolytes.
Sulfur
Selenium
Bromine
Phosphorus

Answer 1

Answer:

Sulphur

Explanation:

Sulphur is the best electrical insulating material known with a resistivity of about 2 × 1023 μΩ-cm. The reason for this large resistivity is probably the electron traps produced by thermal breaking of S8 rings. Electrical conductivity of sulphur is 5.0 × 10–14 S m–1. Electrical conductivity of selenium is 8 × 106 S m–1. Electrical conductivity of bromine is 1.0 × 10–10 S m–1. Electrical conductivity of phosphorous 1.0 × 10–9 S m–1. Thus from this data it is clear that electrical conductivity of selenium is maximum.
