Answer

Explanation:

Step1: Substitute pH value into formula

Given $pH = 5$ and $pH=-\log_{10}(c)$, we have $5 = -\log_{10}(c)$.

Step2: Solve for c

Multiply both sides by - 1, we get $\log_{10}(c)=-5$. By the definition of logarithms, if $\log_{a}(x)=y$, then $x = a^{y}$. Here $a = 10$, $y=-5$, so $c = 10^{-5}$.

Answer:

D. $10^{-5}$
