6. Introduction to brine fluids
Ionic compounds that result from the neutralization reaction of an acid and a base
Dissolved solution of salts, most commonly solvent is water
The ratio of hydroxide ions to hydronium ions determines a solution pH
Formatebrines are the aqueous solutions of the alkalimetalsalts of formic acid. These salts are readily soluble in water, yielding high-density brines
