which of the following $k_{a}$ values would be the strongest acid of the group?\n$2.6\times10^{-4}$\n$1.2\times10^{-7}$\n$3.4\times10^{-6}$\n$8.5\times10^{-10}$
Answer
Answer:
$2.6\times 10^{-4}$
Explanation:
Step1: Recall acid - strength relation
The larger the $K_{a}$ value, the stronger the acid.
Step2: Compare given $K_{a}$ values
We have $2.6\times 10^{-4}$, $1.2\times 10^{-7}$, $3.4\times 10^{-6}$, $8.5\times 10^{-10}$. Among these, $2.6\times 10^{-4}$ is the largest.
