HCl + NaOH → NaCl + H2O
2. If the HCl solution has a concentration of 0.1M, determine the volume of 0.2M NaOH solution required to neutralize it.
n(HCl) = C1*V1 = 0.1M * 0.025L = 0.0025 moles
n(NaOH) = n(HCl) (from the balanced equation) = 0.0025 moles
V2 = n(NaOH) / C2 = 0.0025 moles / 0.2M = 0.0125L
Therefore, 12.5ml of 0.2M NaOH solution is required to neutralize the 25.0ml of 0.1M HCl solution.
a 25.0ml (0.02l) sample of Hcl solution is placed in a flask with few drops of phenolphalein (indicator)
