MISSED THIS? Watch KCV $17\mathrm{.}4$A$,$ KCV $17\mathrm{.}4$B; Read Section $17\mathrm{.}4.$ You can click on the Review link to access the section in your eText. The graphs below labeled $($a$)$ and $($b$)$ show the titration curves for two equal$-$volume samples of bases, one weak and one strong. Both titrations were carried out with the same concentration of strong acid.

Part A

What is the approximate $pH$ at the equivalence point of the curve in $($a$)?$

Express your answer as a whole number.
