Achemical analysis has revealed the following composition for the rain falling on the city of thule: 1.38 mg/l of hno3, 3.21 mg/l of h2so4, and 0.354 mg/l of hcl. hno3, h2so4 and hcl are strong acids, so you can assume that the h is fully released when these acids are dissolved in water. a. calculate the ph of the rain water. assume that the impact of carbon dioxide on ph is negligible. b. based on the ph you obtained in question a, comment if it would be reasonable to neglect the effect of carbon dioxide

pH = 4.19

Explanation:

Let's assume we have 1 L of rain, then we'll have

Now let's convert the mass into moles:

One mol of each of these strong acids is equal to one mol of H⁺, so the total number of H⁺ moles in 1 L of rain is:

The molar concentration of H⁺, or [H⁺], is:

According to EPA, typical acid rain has a pH between 4.2 and 4.4, so in this case it is reasonable to neglect the effect of carbon dioxide, because the calculated pH value is not significantly different than the pH of typical acid rain.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
