Titrations

Titration is the process of slowly adding the titrant solution to the analyte suntil a desired chemical reaction or endpoint is reached (in our case we are aiming for a pH of 5.2 ish). The Titrant is the solution placed in the burette or pipette. We did not use any indicator, simply waited and continued to slowly check the pH drop b drop

In your case:

• L-Arginine = titrant (a strong base)

• Project mist = analyte (slightly acidic due to botanical extracts and sorbic acid)

• Endpoint = pH 4.5

This happened instantly and I had to use 5 drops of citric acid to bring the pH back down from about 5.98 back to 5.23 which worked out perfectly 

This procss included : 

• Adding a known base to an acidic system

• Monitoring the pH change

• Stopping when you hit your target pH
