Question

which has more hydrogen ions - a solution with a ph of 3 or a ph of 12? (1 point)

ph of 3

ph of 12

Explanation:

Step1: Recall pH formula

The formula for pH is $pH = -\log[H^+]$, where $[H^+]$ is the hydrogen - ion concentration. We can rewrite it as $[H^+]=10^{-pH}$.

Step2: Calculate $[H^+]$ for pH = 3

When $pH = 3$, $[H^+]=10^{-3}\ mol/L$.

Step3: Calculate $[H^+]$ for pH = 12

When $pH = 12$, $[H^+]=10^{-12}\ mol/L$.

Step4: Compare the two concentrations

Since $10^{-3}>10^{-12}$, the solution with pH = 3 has more hydrogen ions.

Answer:

pH of 3
