When carbon dioxide dissolves in water, it undergoes a multistep equilibrium process, with Koverall = 4.5x10⁻⁷, which is simplified to the following:(d) If the partial pressure of CO₂ in clean air doubles in the next few decades, what will the pH of rainwater become?

Respuesta :

The entire atmosphere has a pressure of one atmosphere. As a result, the pressure at 700 ppm is 700x[tex]10^{-6}[/tex] atm. So, we can see that doubling CO₂ will result in a 0.15 pH unit decrease in the pH of rain.

What is pH?

  • In chemistry, the pH scale is used to define the acidity or basicity of an aqueous solution.
  • Historically, pH stood for "potential of hydrogen." The pH values of acidic solutions are typically lower than those of basic or alkaline solutions.
  • The hydronium concentration's negative log base 10 is known as 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 10-fold increase in the concentration of hydrogen ions!
