Fig. 13. The relation between final internal and final external concentration 
in the case of carrot root tissue immersed in certain chlorides. (After 
Stiles and Kidd.) 
Then, if i and e represent the final internal and final external 
concentrations respectively, the relation between the two is given 
by the equation 
log i — m log e = log k, 
where log k is a constant.
