Question
Use a calculator when necessary to answer the following questions.a. What is the $\mathrm{p} K_{\mathrm{a}}$ for each $\mathrm{K}_{\mathrm{a}}: 10^{-10}, 10^{-21},$ and $5.2 \times 10^{-5} ?$b. What is the $K_{\text {a }}$ for each $p K_{a}: 7,11,$ and $3.2 ?$
Step 1
So, for each $K_a$ value, we calculate $pK_a$ as follows: For $K_a = 10^{-10}$, $pK_a = -\log(10^{-10}) = 10$. For $K_a = 10^{-21}$, $pK_a = -\log(10^{-21}) = 21$. For $K_a = 5.2 \times 10^{-5}$, $pK_a = -\log(5.2 \times 10^{-5}) = 4.28$. Show more…
