Cupric Sulphate Anhydrous Extra Pure is a white to grayish crystalline powder that serves as a highly concentrated form of copper(II) sulphate, ideal for laboratory applications requiring precise copper ion concentrations. It is commonly used in analytical chemistry, electroplating studies, and as a reagent in qualitative tests for reducing sugars and proteins. Its dehydrated form is especially suited for moisture-sensitive reactions or as a drying agent in certain chemical processes. The extra pure grade ensures minimal contamination, making it reliable for high-accuracy research and educational experiments. Store in a cool, dry environment to prevent rehydration and degradation.
Cupric Sulphate Anhydrous Extra Pure
Primary Uses
- Dehydrated Analytical Reagent
- Used in experiments where water of hydration must be avoided, such as gravimetric analysis and stoichiometric reactions involving dry solids.
- Qualitative Tests for Reducing Agents
- Participates in Benedict’s and Fehling’s tests when hydrated; the anhydrous form is used when precise water control is needed.
- Oxidizing Agent
- Acts as a moderate oxidizer in some organic and inorganic syntheses, especially under dry conditions.
- Desiccant for Specific Reactions
- Used as a drying agent in gas or solvent systems where water must be absorbed or absent.
Secondary Uses
- Thermal and Decomposition Studies
- Employed in labs for thermal decomposition to study CuO formation and analyze endothermic reactions.
- Preparation of Solutions with Precise Molarity
- Ideal for preparing copper(II) sulfate solutions without unknown hydration states, improving analytical accuracy.
- Standard in Calorimetry
- Occasionally used in enthalpy change experiments (e.g., dissolution enthalpy) requiring known anhydrous mass.
