CHEM Test 1 (11th) 21-22

A physically homogeneous system made up by two or more components

• Solution

• Suspension

• Colloid

The ratio solute/solvent is always constant

• True

• False

In a solution, the solute and the solvent do not reach with each other.

• True

• False

The properties of a solution

• are the same as the properties of the solvent

• are not the same as the properties of the solvent

• None of the above

The solute is the substance

• intervening is less proportion

• intervening in high proportion

• intervening always in the same proportion

There are two types of solvents:

• Inerts and polars

• Inerts and reactives

• Reactives and non-polar

It is called the universal solvent

• H₂O

• H₂SO₄

• HNO₃

Explain the chemical meaning of "like dissolves like"

H₂O is a great solvent because:

• it is a polar molecule

• it is a non-polar molecule

• none of the above

In your words define polarity
