The equation for the pH of a substance is pH = –log[H+], where H+ is the concentration of hydrogen ions. Which equation models t
he concentration of hydrogen ions (H+) of a solution whose pH is 7.2? [H+] = log7.2 [H+] = -log7.2 [H+] = mc014-1.jpg [H+] = mc014-2.jpg

Answer:
The concentration of the
in the solution with pH is
.
Step-by-step explanation:
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
![7.2=-\log[H^+]](https://tex.z-dn.net/?f=7.2%3D-%5Clog%5BH%5E%2B%5D)
![[H^+]=antilog[-7.2]](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3Dantilog%5B-7.2%5D)
![[H^+]=10^{-7.2}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-7.2%7D)
![[H^+]=6.3095\times 10^{-8} M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D6.3095%5Ctimes%2010%5E%7B-8%7D%20M)
The concentration of the
in the solution with pH is
