A dilute, aqueous potassium nitrate solution is best classified as a

(1) homogeneous compound

(2) homogeneous mixture

(3) heterogeneous compound

(4) heterogeneous mixture

Dilute, aqueous potassium nitrate solution is best classified as a:

(2) homogeneous mixture

Explanation:

A homogeneous mixture may be a solid, liquid, or volatilized mixture that has a similar proportions of its parts throughout any given sample.

Conversely, a heterogeneous mixture has parts whose proportions vary throughout the sample.

Because it's a combination of water and nitrate and you cannot clearly see the separation within the mixture.

Since aqueous means that it is a combination of water and potassuim, the answer is 2) Homogenous mixture.
