Sodium Hydroxide Pearls are small, solid beads of sodium hydroxide, a strong alkaline compound. They are commonly used in industrial applications, including cleaning, pH regulation, and chemical synthesis. The pearls dissolve easily in water, forming a highly caustic solution that can handle a variety of tasks, from de-greasing surfaces to adjusting the acidity of solutions. They require careful handling due to their corrosive nature and can cause severe chemical burns if not used properly.
Uses of Sodium Hydroxide Pearls
pH Adjustment:
They are used to adjust and maintain the pH of solutions in a range of chemical reactions and processes.
Chemical Reactions:
Sodium hydroxide serves as a reagent in various chemical syntheses and reactions, including saponification (soap-making) and neutralization reactions.
Cleaning:
They are employed to clean glassware and equipment, effectively removing organic residues and contaminants.
Titration:
Sodium hydroxide is used in titrations to determine the concentration of acidic solutions.
Buffer Solutions:
They are used to prepare buffer solutions by reacting with acids to create a stable pH environment.
