Answer 1

Answer:

Saturated solution

A saturated solution is a solution that contains the maximum amount of solute that is capable of being dissolved.

Example

When 30.0 g of NaCl is added to 100 ml of water, it all dissolves, forming an unsaturated solution. When 40.0 g is added, 36.0 g dissolves and 4.0 g remains undissolved, forming a saturate

PURE SUBSTANCE

In chemistry, a substance is pure if it has a homogeneous chemical composition. At the nanoscale, this only applies to a substance made up of one type of atom, molecule, or compound.

Example

pure substances include iron, steel, and water. Air is a homogeneous mixture that is often considered to be a pure substance.
