which of these solutions has the highest concentration of h+? solution a, ph = 12.5 solution b, ph = 7.0…

Answer:

solution C, pH = 2.5

Explanation:

Step1: Recall pH - H⁺ relationship

The formula for pH is $pH=-\log[H^{+}]$, so $[H^{+}]=10^{-pH}$.

Step2: Calculate $[H^{+}]$ for solution A

For solution A with $pH = 12.5$, $[H^{+}]_A=10^{- 12.5}\ M$.

Step3: Calculate $[H^{+}]$ for solution B

For solution B with $pH = 7.0$, $[H^{+}]_B=10^{-7.0}\ M$.

Step4: Calculate $[H^{+}]$ for solution C

For solution C with $pH = 2.5$, $[H^{+}]_C=10^{-2.5}\ M$.

Step5: Compare the $[H^{+}]$ values

Since $10^{-2.5}>10^{-7.0}>10^{-12.5}$, solution C has the highest $H^{+}$ concentration.
