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 . done
Answer
Answer:
2
Explanation:
Step1: Recuerda la fórmula de pH
$pH = -\log[H^+]$
Step2: Sustituye la concentración de iones de hidrógeno
Dado que $[H^+]=0.01 = 10^{- 2}$, entonces $pH=-\log(10^{-2})$.
Step3: Calcula el valor de pH
Según las propiedades de los logaritmos, $-\log(10^{-2})=-(-2)\log(10)$. Como $\log(10) = 1$, entonces $pH = 2$.
