Description

Cresol Red indicator solution is a dark red, aqueous acid-base indicator solution used primarily in titrations and pH measurements. The solution typically contains cresol red dye (o-cresolsulfonphthalein) dissolved in water or a water-alcohol mixture, and it exhibits color changes in specific pH ranges.​ Properties Appearance: Dark red clear solution. pH transition ranges: Acidic range (pH 0.5–2.5): color changes from pink brownish to yellow. Alkaline range (pH 6.5–8.5): color changes from yellow to purple. Dye content in indicator grade is often about 95% purity. Solubility: Miscible with water and soluble in ethanol or dilute acids and alkalis).​ Uses Widely used as a pH indicator in acid-base titrations due to distinct color changes. Useful in diagnostic assays and scientific research involving pH measurements or monitoring. Employed in chemical manufacturing and analytical laboratories to visually detect pH shifts across moderate acidic and alkaline ranges.​ Storage and Handling Store at room temperature in a tightly sealed container, protected from light to prevent dye degradation. Handle with care as the dye may cause skin or eye irritation.​ For catalog description: “Cresol Red indicator solution, dark red clear liquid, pH range 0.5–2.5 (pink to yellow) and 6.5–8.5 (yellow to purple), dye content ~95%, used for pH determination in titrations and assays.”​

Ferrous Ammonium Sulphate Extra Pure (also known as Ammonium Iron(II) Sulfate Hexahydrate or Mohr's Salt) is a pale green to blue-green crystalline solid with the chemical formula FeSO4(NH4)2SO4·6H2O. It is supplied in extra pure grade with high chemical purity, typically 98.5% and above, suitable for analytical and research applications requiring precise and reliable chemical reagents.​ Description for Website Ferrous Ammonium Sulphate Extra Pure is a high-purity crystalline compound of ammonium, iron(II), and sulfate ions, stabilized as a hexahydrate. It is widely used as a primary standard in analytical chemistry for redox titrations due to its stability against oxidation compared to regular iron(II) salts. Its light blue-green crystals are odorless and dissolve readily in water. This reagent is also utilized in dosimetry for measuring gamma radiation exposure, nanomaterials synthesis, and medical applications for iron deficiency treatment.​ Key Features Chemical formula: FeSO4(NH4)2SO4·6H2O Appearance: Pale green to blue-green crystalline powder or crystals Purity: Extra pure grade (typically ≥98.5%) Solubility: Highly soluble in water; stable in air due to ammonium sulfate stabilization Applications: Analytical reagent for redox titrations, primary standard, dosimetry, nanomaterial synthesis, and medical use as an iron supplement Handling: Store in a cool, dry place protected from light; sensitive to air oxidation but more stable than simple ferrous sulfate​ Safety and Stability Extra pure ferrous ammonium sulfate is stable under recommended storage conditions but is sensitive to light and air over long periods. Proper storage and handling practices are recommended to maintain reagent quality.​ This description provides a professional summary suitable for product listings, catalogs, or websites targeting laboratory and industrial customers who require high-purity ferrous ammonium sulfate for precise chemical applications.​
