The reaction between liquid surfaces of different kinds or between liquid and solid surfaces due to surface tension. Its phenomena are greatly modified by electric charging, which alters the surface tension. Capillarity is the cause of solutions creeping, as it is termed. Thus in gravity batteries a crust of zinc sulphate often formed over the edge of the jar due to the solution creeping and evaporating. As a liquid withdraws from a surface which it does not wet, creeping as above is prevented by coating the edge with paraffin wax, something which water does not moisten. It also causes the liquids of a battery cell to reach the connections and injure them by oxidation. The solutions creep up in the pores of the carbons of a battery and oxidize the clamps. To give good connections a disc of platinum or of lead is used for the contact as not being attacked. Another way is to dip the upper ends of the dry and warm carbons into melted paraffin wax, or to apply the wax to the hot carbons at the top, and melt it in with a hot iron.

Tincture of opium, also known as laudanum, refers to a solution of about 10 percent opium alkaloids, such as morphine and codeine, dissolved in alcohol. Historically, it was used as a pain reliever and sedative. This highly addictive substance is a controlled substance due to its potential for abuse and addiction. Despite its dangerous side effects, it is occasionally still used in medicine, particularly in treating severe diarrhea.
