Question

explain me these lines ​

Answer 1

in these lines if the solubility is negative than the solute decrease ultimately and vise-versa

Answer 2

according to le-chatlier principle

Explanation:

solubility is increase with rise of temperature some case eg potassium iodide

some cases it is not valid in case of NaCL

if Nacl is dissolve in water it neither loss energy nor gain energy . means temperature doesnot effect on Nacl .

in case of licl heat is loss means exothermic reaction...
