A solution of potassium chlorate, #KCIO_3#, has 20 grams of the salt dissolved in 100 grams of water at 70 C. Approximately how many more grams of the salt can be added to the solution before reaching the saturation point?
To solve this, let's look at a solubility curve graph:
The curve for
The question says there are
#color(red)(30color(white)(l)"g") - 20color(white)(l)"g" = color(blue)(ulbar(|stackrel(" ")(" "10color(white)(l)"g KClO"_3" ")|)#
can further dissolve before the solution is saturated.
