Question

Which sample is a homogeneous mixture?

Answer 1

NaCl(aq) is a homogeneous mixture.

An aqueous sodium chloride is a homogeneous mixture because NaCl completely dissolves in water, thus giving a single visible phase.

Further Explanation

Mixture  

• A mixture is a substance that is made up of two or more substances that are not chemically combined and in fixed proportions.  
• A mixture may have several varying physical properties.
• There are two types of mixture:

Homogeneous mixtures  

• These are mixtures with a similar uniform appearance and composition throughout. Examples are, steel, air, salt water, etc.
• Homogeneous mixtures may either be, a colloid or a solution.

Solutions  

• Solutions are types of homogeneous mixtures containing two or more substances in a single phase.
• Solutions contains, a solute which is the substance that dissolves in the other substance, and a solvent which is the substances that dissolves the solute.
• For example, in a salt solution, water is the solvent and salt is the solute.

Colloid  

• A colloid is a homogeneous solution that has an intermediate size particles between a suspension and a solution. Examples of colloids are fog and milk.  

Heterogeneous mixtures

• This is a type of mixture that contain different substances or two or more phases of matter.
• The components of heterogeneous mixtures are not uniform such that different samples of the mixture are not identical to each other.  
• Examples of heterogeneous mixtures are; blood, soil, Gravel, etc.

Suspension  

• It is a type of heterogeneous mixture made of larger particles that are visible and normally settles when the mixture is undisturbed.
• Examples include, tomato juice, fine sand, etc.

Answer 2

Answer:

B) NaCl(aq)

Explanation:

Easy way to remember without even understanding the mixtures. Whenever you see aqueous or (aq), that is the correct answer because it is a solution that dissolves in water uniformly distributing the matter.
