In this experiment, you will identify an unknown weak acid by titration with standardized base. This lab takes place in two parts, which you can do in either order: 1. Standardization of a sodium hydroxide solution to find its actual concentration (approximately 0.1 M) 2. Titration of the weak acid with the sodium hydroxide solution. You won't know if your acid is monoprotic (HA), diprotic (H2A), or triprotic (H3A). a.) Indicate how you would differentiate between the three different types...

Workshop 5: Titration Curves A pH or titration curve can be produced by plotting the pH of a solution (containing an analyte) versus the volume of added The equivalence or end point of a titration occurs when enough titrant has been added to consume all the acid or base initially present in the analyte.You know you have reached the endpoint when you see a significant change in the pH of the solution. Part Lets begin by analyzing a titration curve...

Titration of Hydrochloric Acid: 1) Use the buret that is located near the hydrochloric acid container to dispense 25.00 mL of hydrochloric acid solution into a clean dry 100 mL beaker. Record the molarity of this solution on your data sheet. 2) Check to make sure that the volume on your sodium hydroxide buret reads 0.00 mL. If it does not read 0.00 mL, adjust it...
