The graph shows how the solubility of various chemicals varies with temperature. The solubility is measured as grams of dissolved chemical (solute) per 100 grams of water.
Under the assumption that the curves shown continue in the same general shape beyond the plotted area, use the drop-down menus to complete each of the following statements in the manner that most accurately reflects the information provided.
At 60°C, the most soluble of the chemicals is most likely .
There is most likely a temperature above 100°C at which NH4Cl is exactly as soluble as .

1. At 60°C, the most soluble of the chemicals is most likely_______________.
The solubility of different chemicals at 60°C when dissolved in 100 gms of water.
A. KCI - ~ 45gms/100gms
B. KI - ~ 190-200gms/100 gms, since if the graph extends in a similar manner as it is, it will go up, and at 60°C, it would point at some 190-210gms.
C. KNO3 ~ 108gm/100gm
D. NaNO3 ~ 141gm/100gm
E. SO2 ~ 5gm/100gms.
We can see from the above inference that KI is the most soluble of all the chemicals mentioned at 60°C.
Answer B.
2. There is most likely a temperature above 100°C at which NH4Cl is exactly as soluble as_______________.
If the graph for all the 3 is increased above 100°C, the following would increase in the order:
A. KCI - for a long list of temperatures above 100, KCI, would not increase above 70, since the graph will be a similar line its at 100°C.
B. KCIO3- it will increase and coincide with NH4Cl, soon above 100°C, b/w 90-100gm/100gm.
C. NaCI - will never coincide with NH4Cl, since the graph will a straight line after 100°C.
Answer B.
The solubility of different chemicals at 60°C when dissolved in 100 gms of water.
A. KCI - ~ 45gms/100gms
B. KI - ~ 190-200gms/100 gms, since if the graph extends in a similar manner as it is, it will go up, and at 60°C, it would point at some 190-210gms.
C. KNO3 ~ 108gm/100gm
D. NaNO3 ~ 141gm/100gm
E. SO2 ~ 5gm/100gms.
We can see from the above inference that KI is the most soluble of all the chemicals mentioned at 60°C.
Answer B.

1)B,The solubility of different chemicals at 60°C when dissolved in 100 gms of water are:
A. KCI - 45
B. KI ~ 200-220gms since the graph is straight up and it would touch around these values
C. KNO3 - 105
D. NaNO3 - 125
E. SO2 - 4
2)NH4,Cl will match KCLO3 since both are increasing parallely and they will somewhere above 100°C meet at a point or will be most closer
