Chapter 21, Problem 3STP

To determine

To Choose: The correct option.

Answer to Problem 3STP

Option B

Explanation of Solution

The curve of potassium bromide shows that the value of solubility is $100grams$ at ${90}^{0}C$ .

Sodium chlorate has a maximum value of solubility = $200grams$ at ${100}^{0}C$ .

Sodium chloride has a maximum value of solubility = $40grams$ at all temperatures.

Potassium nitrate has a maximum value of solubility = $240grams$ at ${100}^{0}C$ .

Conclusion:

Thus, option B is correct.
