It is a clear, bright blue liquid that saves the time and dust exposure involved in dissolving copper sulfate crystals.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChemical identity.\u003c\/strong\u003e Copper(II) sulfate, also called cupric sulfate, has the formula CuSO4 and a molar mass of 159.60 g\/mol. The familiar bright blue crystals are the pentahydrate, CuSO4·5H2O (249.69 g\/mol). In water both forms give the same blue copper(II) ion solution, so the basis of the 10% figure, anhydrous or pentahydrate, determines the exact copper content.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhy the solution is blue.\u003c\/strong\u003e Copper(II) ions in water are surrounded by water molecules that absorb red and orange light, giving the characteristic blue color. That color makes copper sulfate a staple of teaching demonstrations and gives a quick visual cue when copper is consumed or displaced in a reaction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRedox and displacement chemistry.\u003c\/strong\u003e Copper(II) ions are readily reduced to copper metal by more active metals. An iron nail or zinc strip placed in copper sulfate solution becomes coated with copper while the blue color fades, a classic single-displacement reaction, and the same chemistry underlies zinc\/copper galvanic cells.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectroplating and electrochemistry.\u003c\/strong\u003e Acidified copper sulfate solutions are the basis of acid copper electroplating and of copper coulometers, where copper deposited on an electrode measures the charge passed. In the lab, ready-made copper sulfate solution supplies the electrolyte for plating demonstrations, electrodeposition experiments, and electrochemical cells.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnalytical and test reagents.\u003c\/strong\u003e Copper sulfate is a component of several classic chemical tests and reagents, including reagents for reducing sugars and protein detection, and it serves as a catalyst in some digestion procedures. A standardized 10% solution gives consistent starting strength for preparing these reagents.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReacting with bases and ammonia.\u003c\/strong\u003e Adding a strong base precipitates pale blue copper(II) hydroxide, and adding ammonia first precipitates the hydroxide, then dissolves it to form the deep blue tetraamminecopper(II) complex. These color changes make copper sulfate solution a reliable demonstration and identification reagent.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandling and environmental care.\u003c\/strong\u003e Copper sulfate is harmful if swallowed, irritates the skin and eyes, and is highly toxic to aquatic life with long-lasting effects (H410). Never pour copper solutions down the drain; collect them for disposal as hazardous waste according to local regulations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003ctable style=\"width:100%;
