If is diluted 100 times, what will be its approximate pH? — Ionic Equilibrium Chemistry Question
Question
If $10^{-6} \text{ M } HCl$ is diluted 100 times, what will be its approximate pH?
Answer: B
💡 Solution & Explanation
Diluting $10^{-6} \text{ M } HCl$ 100 times gives $10^{-8} \text{ M } HCl$. The pH of this extremely dilute acid is determined by factoring in water's $H^+$, yielding a pH slightly less than 7 (approx 6.98).
