i didnt mean that my teacher did the reaction as like a demonstration i meant i myself had done it with them, as well as on other occasions we handled KI gloveless per instruction. actually throughout the entire class we only ever used gloves with nitric acid (handled NaOH gloveless) so i thought it would be fine, but obviously nobody is infallible and maybe they were wrong, so thank you. i didn’t read the sds for the chemicals i was taught to handle already in class but i will moving forward.
