The equation for the pH of a substance is pH = -log[H], where Ht 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?

![[H^{+}]](/tpl/images/1387/2661/16f6b.png)
: is the concentration of hydrogen ions.![[H^{+}]_{b} = 10^{-pH} = 10^{-11.2} = 6.31 \cdot 10^{-12}](/tpl/images/1387/2661/fc6e6.png)
![[H^{+}]_{a} = 10^{-pH} = 10^{-2.4} = 3.98 \cdot 10^{-3}](/tpl/images/1387/2661/6bc1a.png)
![\Delta H^{+} = [H^{+}]_{a} - [H^{+}]_{b} = 3.98 \cdot 10^{-3} - 6.31\cdot 10^{-12} = 3.98 \cdot 10^{-3}](/tpl/images/1387/2661/f2a7c.png)
