-Find the hydrogen ion concentration of a solution whose $\mathrm { pH }$ is $6.8$. Use the formula $\mathrm { pH } = - \log \left[ \mathrm { H } ^ { + } \right]$.
A) $1.58 \times 10 ^ { - 7 }$
B) $6.31 \times 106$
C) $- 0.8325089$
D) $0.83250891$

Question

Quizplus · Accepted Answer

The formula to find the hydrogen ion concentration from pH is $[H^+] = 10^{-\text{pH}}$. Substituting $6.8$ for pH, we get $[H^+] = 10^{-6.8} = 1.58 \times 10^{-7}$.
