This experiment we will do a litter research to see if the color swing could be a litter better defined
over a broader humidity range, thus being a little more precise in indicating the humidity value. We
will do a series of trial involving adding and taking away chloride ion from the equilibrium. The chloride
ions involve in the above equilibrium, adding them in or taking them out would affect the color.
Perhaps either fewer or more chloride ions would produce better color changes when the humidity
changes..
