What is the pH value 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.

-1
What is the most common charge of iodine?
Does iodine have a negative charge?
It is easier for iodine to gain an electron rather than to lose 7, so it will form an anion, or negatively charged ion, I− .
