Answer

Answer:

$2.2\times 10^{-5}$

Explanation:

Step1: Find $[H^+]$ for pH = 4.5

Given $pH =-\log[H^+]$, then $[H^+]=10^{-pH}$. For $pH = 4.5$, $[H^+]_1 = 10^{- 4.5}=\frac{1}{10^{4.5}}\approx3.16\times 10^{-5}$.

Step2: Find $[H^+]$ for pH = 5.0

For $pH = 5.0$, $[H^+]_2=10^{-5}=1\times 10^{-5}$.

Step3: Calculate the difference

$\Delta[H^+]=[H^+]_1 - [H^+]_2=(3.16\times 10^{-5}-1\times 10^{-5}) = 2.16\times 10^{-5}\approx2.2\times 10^{-5}$.
