Question

ph measures the acidity of a substance, and is described by the equation $ph = -\log(h^{+})$, where $h^{+}$ is the concentration of hydrogen ions. complete the equation that can be solved to find the ph of a substance with $h^{+}=7.3\times10^{-4}$. $\square=-\log\square$ $ph$ $h^{+}$ $7.3\times10^{-4}$ $10$ $e$

Explanation:

Step1: Recall pH formula

The formula for pH is $pH = -\log([H^+])$.

Step2: Substitute given $[H^+]$ value

Given $[H^+]=7.3\times 10^{-4}$, we substitute it into the formula. So the equation to find pH is $pH = -\log(7.3\times 10^{-4})$.

Answer:

$pH = -\log(7.3\times 10^{-4})$
