International College
Objective
preparing a dilute HCl solution from a concentrated one titrating NAOH solution with HCl solution (of known concentration)
Procedure
Section A: Preparation of 100.0cm3 0.480 mol/dm3 HCl solution
a)Determine the volume of the concentrated acid needed.
b)Introduce a small amount of the concentrated acid solution into a 50cm3 beaker.
c)Add some distilled water into the appropriate volumetric flask from the wash bottle.
d)Using a pipette, take from the beaker the necessary volume of the concentrated acid and admit it into the volumetric flask.
e)Add distilled water to obtain the required volume of the needed solution.
Section B: Preparing the basic solution to be standardized
a)Weigh approximately 2g of NaOH pellets on the electronic balance, and introduce them into 150cm3 beaker.
b)Dissolve the pellets in 100cm3 of distilled water.
c)Cover the beaker with watch glass.
How solution containing NaOH was prepared:
a)Weigh approximately 2g of NaOH pellets on the electronic balance, and introduce them into 150cm3 beaker.
b)Dissolve the pellets in 100cm3 of distilled water.
c)Cover the beaker with watch glass.
d) Insert the solution into burette using a funnel
How solution containing dilute HCl was prepared (preparation of dilute HCL is explained in data collection):
After preparing dilute HCl by determining the volume of the concentrated acid needed, and introducing 4.07 dm3 of the concentrated acid solution into a 100cm3 beaker.
We add some distilled water into the beaker from the wash bottle until the 100 cm3 mark is reached.
