Titrations

A titration is an experimental technique used to determine the concentration of an unknown solution.

A) Buret: Contains the known solutions used to measure how much is added
B) Stopcock: Value used to control the flow of solution from the buret.

C) Pipet: Used to accurately measured the volume of unknown solution

D) Erleameyer Flask: Container for unknown solution

E) Indicator: Used to identify the end point of titration

F) Stock Solution: known  as solution

Example: Determine the concentration of a sodiunm Hydroxide sample so he does a titration with HCL. He gathers the following data. Use the info to determine [NaOH]

Volume Used:
13.1+12.7+12.8+12.8/4= 12.85ml
