Question

What statement is true of acid rain?

a. it has high levels of carbon ions.
b. it does not have enough carbon ions.
c. it has high levels of hydrogen ions.
d. it does not have enough hydrogen ions.

Answer 1

it has high level carbon ions (a)

Answer 2

Acid rain is rainwater that has a pH of less than 5, due to the presence of nonmetal oxides that react with water to produce hydrogen ions, contributing to the acidity of rainwater.

Step-by-step explanation:

Acid rain is rainwater that has a pH of less than 5, due to a variety of nonmetal oxides, including CO2, SO2, SO3, NO, and NO2 being dissolved in the water and reacting with it to form not only carbonic acid, but sulfuric acid and nitric acid. The formation and subsequent ionization of sulfuric acid are shown here:

H₂SO4 (aq)

H₂O(l) + SO3(g) H₂SO4 (aq)

H+ (aq) + HSO4¯(aq)

Based on this information, the statement that is true of acid rain is c. it has high levels of hydrogen ions. Acid rain forms due to the presence of nonmetal oxides that react with water to produce hydrogen ions, contributing to the acidity of rainwater.
