Stu Dent and Doc Inmaking test the acid buffer capacity of their acetic acid – acetate buffer. Help them with their acid buffer capacity calculations. Here is the data for the acid capacity experiment:
25.0 mL of acetic acid – acetate buffer, measured with a pipet
Initial pH = 4.57
5.74 mL of 0.0300 M HCl added, measured using a buret
Final pH = 4.24
Calculate the moles of HCl added to the buffer. (Answer in decimal format with 3 significant figures and units of mol) ?
Calculate the acid buffer capacity of the buffer using moles of HCl per liter of buffer. (Answer in decimal format with 3 significant figures and units of mol/L) ?
