A buffer solution is made by mixing 0.1 M acetic acid (HA) and 0.05 M sodium acetate (A⁻). The pKa of acetic acid is 4.76. Due to an experimental error, the actual pH was not recorded, and we need to solve for the concentration of the conjugate base (A⁻) given that the desired pH should be 4.90. Use the Bisection Method to find the concentration of A.
