How do you test for brine?

Answer 1

To test for brine, you can use a simple conductivity test, as brine (a solution of salt in water) conducts electricity due to the presence of dissolved ions. Alternatively, you can perform a taste test, though this is less scientific, or use a hydrometer to measure the density of the solution; higher densities indicate higher salt concentrations. Another method involves adding silver nitrate, which will produce a white precipitate (silver chloride) if chloride ions are present, confirming the presence of brine.
