Question

Copper metal is added to a solution of silver nitrate. Copper nitrate forms and the colorless solution turns blue. Two of the physical properties of copper nitrate are

A.
blue color and low density.
B.
soluble in water and low boiling point.
C.
low density and low boiling point.
D.
blue color and soluble in water.

Answer 1

The two physical properties of copper nitrate are blue color and soluble in water.

Step-by-step explanation:

The two physical properties of copper nitrate are blue color and soluble in water. When copper metal reacts with silver nitrate, copper nitrate is formed, resulting in a blue color in the solution. Additionally, copper nitrate is soluble in water, meaning it can dissolve in water.

Answer 2

The question gives no information regarding the density or boiling point of copper nitrate, so you can rule out anything that mentions those properties. This leaves D. blue color and soluble in water, which fits because the copper nitrate was in solution and was blue.
