- The pH scale for acidity is defined by pH = - log1o[H] where [H ]is the concentration of hydrog ions measured in moles per liter (M). A solution has a pH of 8.45. Calculate the concentration of hydrogen ions in moles per liter (M). The concentration of hydrogen ions is moles per liter.Numbers 1,2,and 3. Bronsted-Lowry theoryThe pH scale was designed to make it convenient to express hydrogen ion concentrations that are small in aqueous solutions. The definiton of pH is in terms of base 10 logarithms. pH = - log [H*] where [H"] is the hydrogen ion concentration. a If the hydrogen ion concentration in a solution is 1.97 x 10 molL, the pH is b. If the pH of a solution is 3.146, the hydrogen ion concentration is mol/L.

Give all the relevant solutions.Select the correct answers: “Ocean acidification is a process that occurs when atmospheric carbon dioxide dissolves in the ocean and is subsequently converted into (methane; carbonic acid; carbonate ions; sodium carbonite) . This then causes the pH of the ocean to (increase; decrease; fractionate; multiply) and become more acidic.”
