What is the pH of iodine?
This pH value remains constant (7.4) if there is argon purging because the I2 that ultimately forms is sparged from the solution and caught in the thiosulfate trap. On cessation of the irradiation, the pH decreases gradually from what is believed to be hydrolysis of the I2 remaining in solution.
