Vedclass · Answer

(C) When equal volumes of two solutions are mixed,the total volume becomes double the initial volume of each solution.Let the volume of each solution be $V$.Total volume of the mixture = $V + V = 2V$.The concentration of $AgNO_3$ is $0.1 \, M$. Since $AgNO_3$ dissociates completely as $AgNO_3 ightarrow Ag^+ + NO_3^-$,the concentration of $NO_3^-$ ions in the initial solution is also $0.1 \, M$.Using the dilution formula $M_1V_1 = M_2V_2$:$0.1 	imes V = M_2 	imes 2V$$M_2 = \frac{0.1 	imes V}{2V} = 0.05 \, M$.

What is the concentration of nitrate ions if equal volumes of $0.1 \, M$ $AgNO_3$ and $0.1 \, M$ $NaCl$ are mixed together (in $, M$)?
