Answer to Question #63417 in Chemistry for ali jamal abu elrub

Question

suggest an explanation for the fact that the determination of solubility by the analytical method used in A GENERALLY gives a value which falls slightly below the curve obtained in B?

ACCORDING to the solubility curve obtained in this experiment what is the solubility of potassium chlorate in water at 45 c? at 63 c?

would the experimental curve as obtained by the method used in B lie above or below the accepted curve if :(explain each answer concisely)
a)some of the water were lost through excessive heating?

b)some of the solid were spilled and did not dissolve in the water after being weighed?

c)the crystals were not observed promptly?

d) the salt tends to give supersaturated solutions?

Answer 1

a) The water will evaporate due to the heating that will be responsible for its reduction.
b) The solubility of potassium chlorate is temperature dependent. When it is loaded into the water it dissolves in a small amount. Its solubility will increase with increasing temperature.
c) A supersaturated solution necessary for the formation of crystals. In a short time the solution is unsaturated.
d) With increasing temperature increases solubility. Reaching a certain temperature the solution becomes supersaturated and the salt will precipitate.
