I add pure water (at 25 degrees C) and K2CO3 to a flask, then
stopper the flask. I fasten this flask onto a stirrer, turn the
stirrer on, and watch the flask and stirrer continuously for
several hours. At the end of this time, there is still solid
material left at the bottom of the flask. This happens even
though:
I) the stirrer does not stop or change speed;
