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.

- Please answer 5.8arrow_forwardPlease answer 5.6arrow_forwardYou have been tasked with figuring out how to suppress changes in the supply flow rate to a reactorfor which it is desired to keep the inlet flow rate as constant as possible. You are considering designing a surgetank to place upstream of the reactor and then installing a pump on the line between that surge tank and thereactor. A surge tank is one with a weir inside it, which is a partial wall separating the tank volume into twoconnected sections allowing for flow under the weir between the two sections. The variable inlet mass flow,wi(t) flows into volume 1 and then flows due to hydrostatic pressure at a mass flow rate of w1(t) into volume 2.The weir causes a flow resistance, R1, such that w1 = (h1-h2)/R1. Fluid is then pumped out of volume 2 at thedesired constant mass flow rate of w2. Make a summary table of the three transfer functions written in standard form and their keyparameters (gains, time constants) in terms of the physical system parameters (A1, A2, , A, R…).
