Scenario: You are testing two different household solutions with your cabbage indicator, using the color key to the right.

The second solution turns purple. A possible hydrogen ion concentration for this solution is:

A. 1 × 10-2 M

B. 7× 10-3 M

C. 1 × 10-7 M

D. 7 × 10-4 M

i think   the answer is c hope i'm right

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
