What is Salt Brine?

Salt brine is a solution of salt (typically sodium chloride) and water. It has a freezing point lower than pure water and, as such, is a useful tool in reducing the adhesion of snow and ice to road surfaces. The freezing point of brine is a function of the salt being used in the bring (sodium chloride or calcium chloride) and the percentage by weight of the salt in the solution.
