FAQs

Question: What purity and package size apply to these sodium hydroxide pellets?

Answer:The ACS reagent-grade pellets have a titration assay of at least 97% sodium hydroxide and are packaged in 25 kg.

Question: Can the pellets be used to prepare aqueous alkali solutions?

Answer:Yes. Add the pellets cautiously to water with stirring and cooling as needed, because dissolution releases significant heat.

Question: Are these pellets a certified standard volumetric solution?

Answer:No. They are solid ACS-grade sodium hydroxide; any standardized solution requires appropriate preparation and standardization.

Application Note

Thermo Scientific Chemicals Sodium Hydroxide Pellets are an ACS reagent-grade strong inorganic base for laboratory solution preparation, pH adjustment and chemical processing. The solid pellets contain at least 97% sodium hydroxide by titration and are supplied in a 25 kg package. Sodium hydroxide dissolves readily in water with substantial heat release, so controlled addition to water and suitable containment are essential when preparing aqueous solutions. The reagent supports acid–base chemistry and cleaning or preparation steps where sodium hydroxide purity and pellet form are appropriate. This is a corrosive bulk chemical rather than a pre-standardized volumetric titrant. Pellets absorb atmospheric moisture and carbon dioxide; secure storage and suitable protective equipment help maintain usable material quality and safe handling.
