graph the ph function using the graphing utility. then answer the questions. what is the ph of lemon juice that has a hydrogen ion concentration of 0.01 moles per liter? the ph is
Answer
Explanation:
Step1: Recall pH formula
The formula for pH is $pH = -\log[H^+]$, where $[H^+]$ is the hydrogen - ion concentration.
Step2: Substitute the given value
Given $[H^+]=0.01 = 10^{-2}$ moles per liter. Then $pH=-\log(10^{-2})$.
Step3: Use logarithm property
We know that $\log(a^b)=b\log(a)$. So, $-\log(10^{-2})=-(- 2)\log(10)$. Since $\log(10) = 1$, then $-(-2)\times1 = 2$.
