Question
$100 \text{ mL}$ of $0.1\text{ M } AgNO_3$ is mixed with $100 \text{ mL}$ of $0.1\text{ M } NaCl$:
Answer: A,B,C,D
💡 Solution & Explanation
$\text{moles } Ag^+ = 0.01$; $\text{moles } Cl^- = 0.01$. Reaction: $Ag^+ + Cl^- \rightarrow AgCl(s)$. $Na^+$ and $NO_3^-$ are spectator ions. $\text{Final volume} = 200 \text{ mL}$. $\text{Molarity} = 0.01 / 0.2 = 0.05 \text{ M}$ for both.
