### Antacid Titration Lab Calculations

Titration is the process by which one unknown solution’s concentration reacts within a known solution’s concentration (standardized solution). During this experiment, titration was used to calculate the moles of HCl neutralized by the antacid, by knowing the moles of HCl initially added to the flask and moles of HCl neutralized by the NaOH.
