Question 1:
When an acid name ends in -ic acid, there is often a related acid whose name ends in -ous acid. The formula of the -ous acid has one less oxygen atom than that of the -ic acid. With this information, write formulas for:
(a) sulfurous acid and sulfuric acid

(b) nitrous acid and nitric acid.

Question 2:
What is the pH of a solution that has a hydrogen ion concentration of 1.0 * 10 -9 M? Show your calculation.

Question 1:

(a) Sulfurous acid: H2SO3

Sulfuric acid: H2SO4

(b) Nitrous acid: H2NO2

Nitric acid: H2NO3

Question 2:

To calculate the pH, based on concentration of H+ ions, there is one formula:

[tex]ph = - log_{10}(c(h + )) [/tex]

So the pH of this solution is

[tex] - log_{10}( {10}^{ - 9} ) = 9[/tex]

(the solution is basic).
