The pH of solution A is 4.2, while the pH of solution B is 8.2. Find the Hydrogen Ion concentration of Solution A. How much greater is it than that of solution B? (It says to use scientific notation using multiplication symbols in the math palette as needed and to round to the nearest tenth).So pH = -log[H+]. hence [H+] = 10 ^ (- pH)So for solution A, pH = 10 ^ (-4.2) = 6.3 x 10^(-5)For B, pH = 6.3 x 10^(-9)So solution As H+ concentration is 1.0 x 10^4 times greater than solution B.As two digits are used for pH values, we use two digits for the concentration values as well.
