Ndicators are commonly used during titrations to monitor the point at which an acid has fully been converted to its conjugate base (or when a base has fully been converted into its conjugate acid). Its important to pick the proper indicator so that its one color in the beginning, and a different color once the acid or base has been fully converted. For example, in the titration of 1.0 M HCl, you start with only HCl and it gets converted to Cl- by the addition of strong base (HCl + NaOH → NaCl + H2O). What is the pH in the beginning of the titration when you have 1.0 M HCl? What is the pH when all of the HCl has been converted to NaCl? In the titration of 1.0 HF, you start with only HF and it gets converted to F- by the addition of strong base (HF + NaOH → NaF + H2O). What is the pH in the beginning of the titration when you have 1.0 M HF? What is the pH when all of the HF has been converted to NaF? Curcumin (found in turmeric) is an indicator with a pKa of 8.0 that turns from yellow to red. Would curcumin be a good indicator to monitor the titration of HCl? Would curcumin be a good indicator to monitor the titration of HF?
