Question

Given four beakers labeled A, B, C, and D.

Add 40 mL of distilled water to beakers A and C.

Add 40 mL of the prepared sodium acetate/acetic acid buffer solution to both beakers B and D.

Pipette 1.0 mL of 6 M HCl, hydrochloric acid solution into beakers A and B.

Pipette 1.0 mL of 6 M NaOH, sodium hydroxide solution into beakers C and D.

If the concentration of CH3CO2Na after dilution is 0.62M and the concentration of CH3CO2H after dilution is 0.51M

Calculated pH of beaker A and B after the addition of 6 M HCl.(Ka of CH3CO2H=1.32x10^-4)
