Sodium Hydroxide Pellets ER Qualigens, 500g

Q: How should Sodium Hydroxide Pellets ER Qualigens be stored?

A: Store the pellets in a tightly sealed plastic bottle, in a cool and dry environment, away from moisture and incompatible substances. This is critical because the product is deliquescent and will absorb water from the air, potentially compromising purity and performance.

Q: What is the main benefit of using ER (Extra Pure Reagent) grade Sodium Hydroxide in the laboratory?

A: Using ER (Extra Pure Reagent) grade ensures exceptional purity (98%), reducing the risk of contaminants in sensitive experiments. This leads to reliable, reproducible results, which are vital for precise laboratory research and analytical work.

Q: When is Sodium Hydroxide typically used during laboratory procedures?

A: Sodium Hydroxide is commonly applied in titration processes, pH adjustment, sample digestion, and chemical synthesis during laboratory work. Its strong basicity (pH 11) makes it an essential tool for neutralization and separation techniques.

Q: Where can Sodium Hydroxide Pellets ER Qualigens be applied?

A: These pellets are suitable for use in chemical laboratories, research institutions, pharmaceutical quality control, and environmental analysis, wherever a high-purity base is essential for reliable experimental outcomes.

Q: How are the Sodium Hydroxide pellets used in laboratory processes?

A: Measure the required quantity of pellets and dissolve in water, following laboratory safety protocols. Use the prepared solution as a reagent for titration, cleaning, or pH regulation in various experiments.

Q: What is the typical shelf life of this product and does it require special handling?

A: The pellets have a shelf life of 60 months when stored properly. Due to their high reactivity with moisture, handle them with gloves and close the container immediately after use to preserve quality.

Q: Why is the appearance of Sodium Hydroxide described as 'deliquescent'?

A: The term 'deliquescent' indicates that the pellets strongly attract and absorb water from the air, which can cause them to dissolve if exposed. This property necessitates storing them in airtight containers to maintain their solid form and purity.
