The dominant species present in water if the ph is held constant at ph = 8 is .
The pH scale is used in chemistry to determine whether an aqueous solution is basic or acidic. Historically, pH stood for "potential of hydrogen." The pH values of acidic solutions are typically lower than those of basic or alkaline solutions.
A solution's pH is a significant indicator of its chemical composition. The pH can affect how readily available nutrients are, how biological processes work, how bacteria behave, and how chemicals behave. The negative log base 10 of the hydronium concentration is used to define pH. The pH is a logarithmic indicator of how many hydrogen ions are present in a solution. Since pH is measured on a log scale, a pH increase of 1 equates to a 10x increase in the concentration of H+ ions.

Step first:
Since, 78.0 percent by volume is present in the air which implies there are 78 moles of
present in 100 moles of air.
Now,
Mole fraction of =
Mole fraction =
= 0.78
Partial pressure is equal to the multiplication of total pressure and mole fraction.
Partial pressure = (as 1 atm is atmospheric pressure)
= 0.78 atm.
Step second:
Henry's law constant is calculated by:
where,
is solubility of gas
is partial pressure of gas
is henry's law constant
Substitute the value of solubility and partial pressure to find the value of Henry's law constant in above formula:
k =
=
Thus, Henry's Law constant is .
