Please show work thank you very much Title: Calculating pH of Various Solutions**Objective:** Calculate the pH of the following solutions:a) **Solution Composition:** - 0.070 M in potassium propionate (C₂H₅COOK) - 0.085 M in propionic acid (C₂H₅COOH) - Note: $K_a$ for propionic acid is $1.3 \times 10^{-5}$.b) **Solution Composition:** - 0.085 M in trimethylamine (CH₃)₃N - 0.10 M in trimethylammonium chloride (CH₃)₃NHCl - Note: $K_b$ for trimethylamine is $6.4 \times 10^{-5}$.c) **Solution Construction:** - Made by mixing 25.0 mL of 0.20 M acetic acid and 25.0 mL of 0.25 M sodium acetate.**Instructions:**1. For solution (a), determine the pH by considering the relationship between the concentrations of the acid and its conjugate base, applying the Henderson-Hasselbalch equation.2. For solution (b), calculate the pH using the concentration of the weak base and its salt, employing the Henderson-Hasselbalch equation for bases.3. For solution (c), first identify the moles of acetic acid and sodium acetate mixed. Use the Henderson-Hasselbalch equation to find the resulting pH post-mixing.

Volumetric pipets are calibrated in a manner that takes into account the solution which remains at the tip. True Using the pipettor, you should turn the wheel on the pipette, draw up the solution until the meniscus is several centimeters above the calibration line, then quickly remove the pipette and put your thumb over the open hole of the pipet. True When the bottom of the meniscus coincides with the calibration mark, your pipet contains a precisely measured volume. True e Do not force the pipet into the pipettor, be gentle. Excessive force may cause the pipet to break and could potentially cut you while trying to insert or remove the pipet.…
