Copper Hydroxide Extra Pure is a finely powdered, blue-green compound used in laboratory settings for analytical, inorganic, and qualitative chemistry applications. Its high purity makes it ideal for precipitation reactions, synthesis of copper-based compounds, and studies involving hydroxide ion behavior. In educational labs, it demonstrates typical base-metal hydroxide characteristics, such as low solubility and reactivity with acids to form copper salts. Due to its instability under light and air, it should be handled with care and stored in well-sealed, light-resistant containers to maintain its integrity for reliable experimental outcomes.

Copper Hydroxide Extra Pure

Primary Uses

Precursor for Other Copper Compounds
- Used to prepare copper salts (e.g., copper sulfate, copper acetate) through controlled acid reactions.
Analytical Chemistry Reagent
- Employed in qualitative analysis for detecting reducing sugars (e.g., in Fehling’s and Benedict’s tests after formation of cupric ions).
Base for Synthesis in Inorganic Chemistry
- Used in the formation of coordination complexes and as a source of Cu²⁺ ions in controlled reactions.
Demonstration of Double Displacement Reactions
- Commonly used in teaching labs to show precipitation reactions (e.g., copper sulfate + sodium hydroxide → Cu(OH)₂).

Secondary Uses

Pigment Precursor in Material Science Studies
- Studied in synthesis of cupric oxide (CuO) through thermal decomposition for use in ceramics and pigments.
Model Compound in Coordination Chemistry
- Investigated for its geometry and behavior in ligand binding experiments and spectroscopy studies.
Demonstrations in pH-Dependent Solubility
- Shows amphoteric behavior: dissolves in strong acids and bases, useful for pH and solubility teaching.
Electrochemical Research
- Sometimes used to prepare copper electrodes or for redox studies involving Cu(II)/Cu(I) transitions.
