Welcome to the article At 283 K a saturated solution of solid X can be prepared by dissolving 21 0 g of it in 100 g of water The. On this page, you will learn the essential and logical steps to better understand the topic being discussed. We hope the information provided helps you gain valuable insights and is easy to follow. Let’s begin the discussion!

At 283 K, a saturated solution of solid X can be prepared by dissolving 21.0 g of it in 100 g of water. The maximum amount of X that can be dissolved in 100 g of water at 313 K is 62.0 g. An attempt is made to dissolve 50.0 g of X in 100 g of water at 313 K.

A) All the 50.0 g of X will dissolve at 313 K.
B) At 313 K, 29.0 g of X will remain undissolved.
C) Solubility of X decreases with an increase in temperature.

Which of the above statements are correct?

a) A & B
b) A only
c) B & C
d) A & C

Answer :

Final answer:

The correct statements are: B) and C).

Explanation:

The correct statements are: B) At 313 K 29.0 g of X will remain undissolved. C) Solubility of X decreases with increase of temperature.

Based on the given information, we know that at 313 K, the maximum amount of X that can be dissolved in 100 g of water is 62.0 g. Since 50.0 g of X is less than the maximum solubility, it will not all dissolve. Therefore, statement B is correct.

Additionally, we are told that at a higher temperature of 313 K, the maximum solubility of X decreases from 62.0 g to a lower amount. This indicates that the solubility of X decreases with an increase in temperature. Therefore, statement C is also correct.
