Consider a membrane with a surface potential of -100 mv. assume the membrane is a flat sheet. the salt concentration of the medium is 50 mm kcl and 5 mm mgcl2. the ph of the medium is 7.0.
a. plot the electrical potential, the [k+], the [cl-], and the ph as a function of distance from the membrane.
b. plot the charge density as a function of distance from the membrane.
c. estimate the charge per unit area of the membrane from the charge density plot.
d. plot the magnitude of the electric field as a function of distance from the membrane.
this is physics practice not biology
