calculate the h+ when ph = 4? enter scientific notation like this: 6.02e23.
Answer
Explanation:
Step1: Recall pH formula
The formula for pH is $pH = -\log_{10}[H^+]$. We can rewrite it to solve for $[H^+]$ as $[H^+]=10^{-pH}$.
Step2: Substitute pH value
Given $pH = 4$, substitute it into the formula $[H^+]=10^{-4}$. In scientific - notation, this is $1.0E - 4$.
Answer:
$1.0E - 4$
