On the other hand, Stannard (1939) found no such pH effect involved in azide inhibition of respiration of active frog muscle. Experiments were performed at pH to determine the toxic level of azide concentration. It was found that in M/250 azide nearly all the cells were injured within two hours (five out of five experiments)..
