How would you prepare 1.56L of a 0.120 M NaOH solution from a
1.20 M
NaOH solution?
A flask contains 55.0 mL of a hydrochloric acid solution. The
molarity of the solution is not known. It
takes 23.5 mL of a 0.103 M sodium hydroxide solution to complete
the reaction with hydrochloric acid. What is the molarity of the
hydrochloric acid solution?
How would you make a 1.75M solution of sucrose using solid
sucrose, a 2mL graduated pipet, and a 25mL volumetric flask?
How would you make a 0.500M solution of sucrose by diluting the
solution in the previous question?
Describe how to make a 600. mL of 0.200 M NaOH from the stock
solution of 2.00 M NAOH solution.
Describe the proper technique/procedure for filling a buret.
Explain why this procedure is necessary.
What would be the ?nal pH if 0.0100 moles of solid NaOH were
added to 100 mL of a bu?er solution containing 0.600 molar formic
acid (ionization constant = 1.8 × 10?4) and 0.300 molar sodium
formate
A)how would you prepare 250 ml of a 0,150 m solution of CoCl2
from solid CoCl2 and distilled water?
b)using the solution from part a and ditilled water,how would
you prepare 100 ml of a 0.0600m solution of CoCl2?
c)What absorbance would you expect from the solution from part b
at the wavelength of maximum sensitivity?
Using your calculated concentration of NaOH from lab how many
grams of KHP would you need to start with in order to have an end
point at 35.00 mL?
Do I use 71.08 or 204.22 for KHP Molecular Mass? Concentration
of NaOH from the Experiment was .356.
How will you prepare 250 mL of 0.01 M NaOH from NaOH pellets?
Please describe in detail how to properly handle,
weight, and dissolve the NaOH pellets, and how you would store the
solution
Show how you would find the concentration of a diprotic acid that
was titrated with NaOH? Find the concentration of a diprotic acid
when 24.55mL of the acid requires 32.57 mL of 0.1059 M NaOH.
