100mL of 0.1M of HCl is added to an antacid tablet to produce a solution
This solution is titrated by 0.1M NaOH. 4.6mL of NaOH is required to neutralize this solution
Does this mean that 4.6mL of HCl was NOT originally neutralized by the antacid?
Titration Question?

✔ 最佳答案
Yes.HCl and NaOH react in mole ratio 1 : 1. As HCl and NaOH are both 0.1 M, 4.6 mL of NaOH reacts with 4.6 mL of HCl which is left unreacted with the antacid.
Hence, volume of HCl reacted with the antacid = 100 - 4.6 mL = 95.4 mL
