Final answer:
Mutually soluble liquids that mix to form clear solutions in any proportion are called miscible. This is a key concept in Chemistry that helps predict whether different liquids can form homogenous mixtures, with ethanol and water being a common example.
Step-by-step explanation:
Mutually soluble liquids that can be mixed together to form clear solutions are referred to as miscible. Examples of miscible liquids include ethanol and water, which can be combined in any proportion to form a homogenous mixture. Infinite mutual solubility describes the ability of miscible liquids to mix in any ratio without becoming a saturated solution. The concept of 'like dissolves like' often explains the miscibility of substances, where polar liquids dissolve polar substances, and nonpolar liquids dissolve nonpolar substances due to the nature of intermolecular attractions.
Miscible contrasts with immiscible liquids, which are substances that do not mix to form a solution, such as oil and water. Meanwhile, substances like n-butanol and water are partially miscible, as they form a clear solution up to a certain concentration. Understanding the miscibility of liquids is essential in creating solutions, whether in scientific experiments or practical applications like antifreeze or fuel mixtures used in outdoor power equipment.
