If normal rainfall has a pH of 6.2 and acid rain has a pH of 2.8, how much greater is the hydrogen ion concentration of the acid rain compared to normal rainfall?

Taking into account the definition of pH, the hydrogen ion concentration of the acid rain is 1.58×10⁻³ greater compared to normal rainfall.

pH is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.

The pH is defined as the negative base 10 logarithm of the activity of hydrogen ions, that is, the concentration of hydrogen ions or H₃O⁺:

pH= - log [H⁺]= - log [H₃O⁺]

Normal rainfall has a pH of 6.2. Replacing in the definition of pH:

6.2= - log [H⁺]

Solving:

[H⁺]= 10⁻⁶ ²

[H⁺]= 6.31×10⁻⁷

Acid rain has a pH of 2.8. Replacing in the definition of pH:

2.8= - log [H⁺]

Solving:

[H⁺]= 10⁻² ⁸

[H⁺]= 1.58×10⁻³

To know how much greater is the hydrogen ion concentration of the acid rain compared to normal rainfall, you must do the subtraction between both concentrations:

1.58×10⁻³ - 6.31×10⁻⁷= 1.58×10⁻³

It is practically equal to the concentration of hydrogen ions in acid rain because its concentration is much higher than the concentration in normal rainfall.

In summary, the hydrogen ion concentration of the acid rain is 1.58×10⁻³ greater compared to normal rainfall.

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
