Copper Hydroxide Extra Pure
Original price was: $ 18.95.$ 18.75Current price is: $ 18.75.
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.
