How long is sodium hydroxide solution good for?
The shelf life of a sodium hydroxide solution is roughly 30 days when properly stored in a dark, cool place.
Is NaOH solution stable?
What are the stability and reactivity hazards of sodium hydroxide? Chemical Stability: Normally stable. Conditions to Avoid: Water, moisture or humidity. Incompatible Materials: Highly reactive.
Where should NaOH solution be stored?
Sodium hydroxide stock solutions should be stored in plastic containers. Glass containers should be completely avoided in the preparation and storage of sodium hydroxide solutions.
Does NaOH break up in solution?
Net Ionic Equations Are Important HCl, NaOH, and NaCl are all strong electrolytes. As such, they dissociate completely into their ions in solution, and although we might write “HCl” we really mean “H+ + Cl–”. Similarly, “NaOH” is “Na+ + OH–” and “NaCl” is “Na+ + Cl–”.
Does sodium hydroxide need to be refrigerated?
If sodium hydroxide is not stored at temperatures above 60° F, the chemical will crystalize and turn solid, resulting in unnecessary chemical waste and damage to the storage system itself.
Does sodium hydroxide lose potency?
Sodium hydroxide lye is used to make solid soap, and potassium hydroxide lye is used to make liquid soap. The lye also needs to be kept in a cool place. It may lose its potency if stored in warmer temperatures.
Is NaOH stable in water?

Can you pour NaOH down the drain?
Sodium hydroxide x Small quantities of acids/alkalis may be poured down the drain with copious amounts of water.
What happens when sodium is at room temperature?
Phase at room temperature: Solid. Melting point: 208.04 degrees Fahrenheit (97.80 degrees Celsius)
What happens to sodium at room temperature?
Sodium is a chemical element with symbol Na and atomic number 11. Classified as an alkali metal, Sodium is a solid at room temperature.
Is sodium hydroxide a weak or?
Sodium hydroxide (NaOH) is strong base because it fully dissociates in water to produce hydroxide ions. While ammonia (NH3) is weak base because it accepts protons from water to produce fewer hydroxide ions in solution.
What is the viscosity of sodium hydroxide?
Sodium hydroxide, NaOH, as a fluid solution, demonstrates a characteristic viscosity, 78 mPa·s that is much greater than water (1.0 mPa·s) and near that of olive oil (85 mPa·s) at room temperature.
What are the common uses of sodium hydroxide?
It is generally used as a solid or a 50% solution. Other common names include caustic soda and lye.Sodium hydroxide is used to manufacture soaps, rayon, paper, explosives, dyestuffs, and petroleum products.
What is sodium hydroxide at room temperature?
At room temperature, sodium hydroxide is a white crystalline odorless solid that absorbs moisture from the air. It is a manufactured substance. When dissolved in water or neutralized with acid it liberates substantial heat, which may be sufficient to ignite combustible materials. Sodium hydroxide is very corrosive.
What happens when sodium hydroxide dissolves in water?
Similar to the hydration of sulfuric acid, dissolution of solid sodium hydroxide in water is a highly exothermic reaction where a large amount of heat is liberated, posing a threat to safety through the possibility of splashing. The resulting solution is usually colorless and odorless.
