A titration is carried out to determine the concentration of the acid in an old bottle of aqueous HCl whose label has become unreadable.
What is the HCl concentration if 61.7 mL of 0.150 M NaOH is required to titrate a 20.0 mL sample of the acid?
Homework Answers
The reaction is given as :
HCl + NaOH = NaCl + H2O
So by using the formula M1V1 = M2V2
where M is Molarity and V is the volume
By putting all the values we get :
0.150 x 61.7 = M2 x 20.0
M2 = 0.463 M
So the molarity of the acid will be 0.463 M

A chemist had a bottle of HCl (aq) of unknown concentration. She performed a titration experiment in order to determine its concentration. She pipeted 25.00 mL of the HCl solution into an Erlenmeyer flask. She then added about 21 mL of deionized water and 3 drops of phenolphthalein indicator dye to the flask. She titrated this mixture with 0.09063 M NaOH (aq), and obtained a permanent, pale pink endpoint after the addition of 36.68 mL of NaOH (aq). Given that...

In this experiment an EDTA titration was performed. Another common type of titration is an acid-base titration. Specifically, a neutralization titration can be used to determine the concentration of a strong acid if it is titrated with a strong base whose concentration is known. This method uses stoichiometry to determine the unknown acid's concentration. Let's say a student had 1.0 M sodium hydroxide ( a? ) and found a solution of sulfuric acid 2 04) whose label had faded. She...
