Question

i need help!! this is the last part i have to do and i have no idea how help!

PART II - Preparation of a 1:1 Buffer 16.1 ml Volume of acetic acid (used to create the titration curve) Volume of NaOH to reach the equivalence point Volume of NaOH required to make a 1:1 buffer (1/2 of the equivalence point volume) 8.1 ml To make a larger quantity of buffer, multiply each of these by six. Swe& Continue 600 mL Use the volumes above x 6 for the calculations in this part. 96.6 mL Volume of acetic acid used to make the buffer. Volume of NaOH used to make the buffer. Concentration of Stock Acetic Acid (calculated in Part 1 and entered above) 0.0154 M Show the NIE (for making the buffer) OH(aq) + CH3COOH(aq) + CH3COO (aq) + H20 (1) XX BI * 12 NaOH(aq) + CH3CHOOH(aq) - CH3CHOON (aq) + H20 Show how you calculated the stoichiometric concentrations of HAC and Ac in the buffer (ICE Table and any calculations) X U BI IX . 2

Answer 1

Number of moles of NaOH used to make the buffer	0.00924 moles
Number of moles of acetic acid used to make the buffer	0.00924 moles
Total volume after NaOH and acetic acid has been mixed	696.6 mL
Stoichiometric concentration of acetic acid in buffer	0.01326 (M)
Stoichiometric concentration of acetate ion in buffer	0.02304 (M)
