i need a typed up lab report on neutralization titration acid basr
Boil distilled water to ensure the removal of CO2
CO2(g) + H2O H2CO3(g)
Using the boiled water, prepare the following
500 mL of 0.1 M HCl from concentrated HCl.
500 mL of 0.1 M NaOH from concentrated NaOH.
Calculate the amount of 0.1 M NaOH that would be
required to neutralize 35 mL of 0.1 M HCl.
• Fill a 50.0 mL buret with about
45 mL of 0.1 M NaOH and cover
the top with a small beaker.
• Fill a second buret with about
20.0 mL of 0.1 M HCl.
Use a double buret clamp if
available so that a back titration
is easily performed as needed.
Titration of HCl with NaOH
Add about 25 mL of 0.1 M HCl into a conical flask and
add two drops of phenolphthalein.
Titrate the HCl sample with NaOH until the solution is
Add HCl from the buret dropwise to discharge the color
Carefully add base until the solution acquires a faint pink
hue that persists for at least 30 seconds
Record & Report the Results
Record the volume of NaOH required to neutralize the
Repeat the titration two-three more times to obtain high
Determine the mean Acid/base ratio & standard
Report 95% confidence interval (CI) and the coefficient of
Do not discard your 0.1M HCl and NaOH solutions. You
will need them for the next experiment.
Expectation in the Conclusion
In a narrative fashion, report the following information

Work under the hood with concentrated acids and
For dilutions always carefully add acid to water; never
Do not remove these substances from under the
Ware gloves when handling these substances.
Report immediately any accidental exposure to
these substances to the lab instructor.
