Question

Assume you have a burette containing a known volume and concentration of a standardized NaOH solution. If you wish to know the concentration of a sample of HCl solution using titration methods, you would also need to know:


the mass of the HCl measured into the flask

the initial volume of the HCl solution in the flask

the temperature of the HCl used to reach the end point of the titration

the concentration of previous titrations performed with the NaOH solution
