Chlorination of rhodium sponge

Chlorine was used to displace air from the tube at lower temperatures (the rate of reaction is minimal at less than 400 C). The reaction depends upon diffusion of hot chlorine into the rhodium sponge, so periodically rotating the tube (caution! the glass will not appear hot in well-lit conditions!) helps complete the chlorination.
