Question- Blood plasma is the solution remaining after cells (red, white, etc...) are removed from whole blood. The clinical analysis of free calcium in plasma can be down with a calcium liquid membrance ion-selective electrode. When combined with a proper reference electrode, the calcium ISE gave the following potentials in a buffered solution:
0.00240 M E= 0.243V
0.000160 M E= 0.208V
a) What is the concentration of calcium in the blood plasma?
b) Describe the chemical makeup of the liquid membrane
I need expert help to solve the above question. Show each and every step.
