SACE Stage 1 Chemistry - 4.1 Miscibility and Solutions (Part 1)

In a solution, which statement accurately describes the solute and solvent?

• The solute is the substance that does the dissolving and is present in a greater amount.

• The solvent is the substance that gets dissolved and is present in a lesser amount.

• The solute is the substance that gets dissolved and is present in a lesser amount.

• Both the solute and solvent are present in equal amounts.

What is a key characteristic of a polar substance?

• It has a symmetrical distribution of charge.

• It results in partially positive and negative ends.

• It is primarily composed of carbon and hydrogen atoms.

• It does not form intermolecular forces.

What happens when two liquids are immiscible?

• They form a single homogeneous liquid.

• They form separate layers.

• They form intermolecular forces of similar or greater strength.

• One liquid dissolves completely into the other.
