continuing.
④ Titrate the unknown solution with 0.1M NaOH solution until the first permanent appearance of the tint blue color of the indicator(BTB). Read the buret volume to 0.01 mL
⑤ Repeat steps 1-4 two more times for a total of three titrations.
⑥ Calculate the average molarity of acid(yM) in unknown solution from these three titrations and the % relative standard deviation.
First star I see tonight
"I wish I may, I wish I might"
I forget the rest.
But please help me tomorrow night.
Im gonna show you
how I used to sneak out when I was a kid.
I was really hot to see my girlfriend,
Francie, but Ma didnt like her.
Why not?
Cause Francie was married,
and I was and a half.
Come here.
Twenty-two feet.
Me and Bella dug it ourselves.
Bella did?
I just told her China was on t
Objectives
• Use density to calculate the apparent molar
volumes of sodium chloride solutions of varying
concentrations. The densities will be measured
through the use of pycnometers.
• Make a plot of the apparent molar volume as a
function of concentration. Use this graph to
determine the partial molar volume of the solute,
sodium chloride, at various concentrations.

FADE IN:
EXT. TOWN - NIGHT
The hanging sign says Entering Cherry Falls, Ohio
We see Cherry Falls - A small town in rural Northeastern Ohio. This is

town. But things are hidden here. The barns are locked, the shades are
drawn.

Kevlar vest, drop a Colt .45 into a shoulder holster, and a
.38 into an ankle holster. She straightens up, approaches
the men and lays a street plan across the hood of one of
their cars.
