Problem 14-D

One glass-membrane sodium ion-selective electrode has a selectivity coefficient . When this electrode was immersed in 1.00 mM NaCl at pH 8.00, a potential of 38 mV (versus S.C.E.) was recorded. (a) Neglecting activity coefficients, calculate the potential with Equation 14-10 if the electrode were immersed in 5.00 mM NaCl at pH 8.00. (b) What would the potential be for 1.00 mM NaCl at pH 3.87? You can see that pH is a critical variable for the sodium electrode.

Step 1 of 3

Isolation of Eugenol from Cloves The purpose of the lab is to use distillation and extraction to separate and isolate eugenol from the cloves. 1. Set up distillation apparatus 2. Obtain ~0.5 g of cloves in around bottom flask. Add in 50 mL of DI water and a boiling chip. Heat mantle and place the round bottom flask on top. Heat gradually until the solution boils. 3. In a 50 mL graduated cylinder, collect ~30 mL of distillate. Place the graduated cylinder in an ice bath. If no separation occurs. Extract the aqueous layer with two portions of 10 mL DCM. 4. Combine both organic layers; add in sodium sulfate (drying agent). Decant the solution by transferring the organic layer into a tarred vial, but leave the solids out. 5. Use a hot
