The equation for the pH of a substance is pH = –log[H+], where H+ is the concentration of hydrogen ions. A basic solution has a pH of 11.2. An acidic solution has a pH of 2.4. What is the approximate difference in the concentration of hydrogen ions between the two solutions?
a) 1.6*10^9
b) 4.0*10^3
c)6.7*10^1
D)1.6*10^11

Best ResponseYou've already chosen the best response.0hints: pH=log[H+] (log base 10) take the inverse [H+]=10^(pH) So you can calculate [H+] for each case and take the difference.
