100 mL of is mixed with 100 mL of : — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

Acid and base neutralize to form $NaCl + H_2O$. Since moles are equal ($10 \text{ mmol}$ each), it is neutral. $\text{Final volume} = 200 \text{ mL}$. $[Cl^-] = 10 / 200 = 0.05 \text{ M}$. Same for $[Na^+]$.
