Question

use the following information to answer the next question
the following statements were made about solubility
1 polar compounds dissolve in polar compounds
2 compounds with hydrogen bonding dissolve in water
3 non - polar compounds dissolve in non - polar compounds
4 non - polar compounds dissolve in water
5 polar compounds will dissolve in octane, c8h18(l)
6 non - polar compounds will dissolve in octane, c8h18(l)

1. based on the solubility rules, which statements are correct:

(record your four - digit answer in the numerical - response section below.)
your answer: □□□□

Explanation:

Step1: Recall solubility principle

Like - dissolves - like. Polar substances dissolve in polar solvents and non - polar substances dissolve in non - polar solvents. Water is a polar solvent and octane ($C_8H_{18}$) is a non - polar solvent.

Step2: Analyze each statement

1. Polar compounds dissolve in polar compounds. This is correct according to the like - dissolves - like principle.
2. Compounds with hydrogen bonding dissolve in water. Water has hydrogen bonding and can form hydrogen - bonds with other compounds having hydrogen - bonding capabilities, so this is correct.
3. Non - polar compounds dissolve in non - polar compounds. This is correct by the like - dissolves - like rule.
4. Non - polar compounds do not dissolve in water (a polar solvent), so this is incorrect.
5. Polar compounds do not dissolve in octane (a non - polar solvent), so this is incorrect.
6. Non - polar compounds will dissolve in octane. This is correct as octane is non - polar and non - polar compounds follow the like - dissolves - like rule.

Step3: Identify correct statements

The correct statements are 1, 2, 3, 6.
