·A· sample of a white solid is known to be ${\mathrm{NaHCO}}_3$, ${\mathrm{AgNO}}_3,{\mathrm{Na}}_2\mathrm{S}$, or ${\mathrm{CaBr}}_2$ Which 0.1 M aqueous

solution can be used to confirm the identity of the solid?

One of the six primary strong mineral acids used in chemistry is hydrochloric acid. Because stronger acids can be employed as the preferred acid in titration to determine the number of bases additionally it is an effective acidifying reagent.

Hence, option B is correct.
