Copper sulfate has a wide range of functions, and has important uses in industry, electroplating, and agriculture. How to identify the good quality of copper sulfate and how to distinguish it? Copper sulfate identification can start from the following two aspects, and adopt corresponding methods according to the actual situation of the customer.

  1. Precise method
    This method mainly uses chemical methods and is suitable for companies, research institutes and other units with laboratories. The details are as follows: Take the pre-grinded sample and CuSO4.5H2O each about 1 gram (the size of peanuts), put them into two water cups, add 100 ml of clean water, and shake for a few minutes until the crystals are completely dissolved. Measure about 5 ml of each of the above turbid liquids, put them in two glass cups, add about 0.5 g of ammonium bicarbonate to both, shake for 1 to 2 minutes to fully react and develop color. After standing for 10 minutes, observe and compare . If the color of the two solutions is the same, there is no precipitation and there is little precipitation, the sample is qualified; if the blue color of the sample solution to be tested is significantly lighter than the pure product, it means that its active ingredient content is low, and it may contain some sodium , Magnesium, potassium and other impurities; if there is a large amount of precipitation in the sample, it means that the sample contains more impurities such as iron, aluminum, zinc or calcium. The more the precipitation, the lower the effective component.
  2. Simple visual inspection
    This method can only be used as a simple reference for individuals without testing conditions or emergency judgment. The specific method is as follows, using the multi-point sampling method to collect copper sulfate samples and observe the crystal color. CuSO4.5H2O is a triclinic crystal, and its crystal block should be blue. If it contains impurities such as sodium and magnesium, the color of the crystal block will gradually fade with the increase of the impurity content. If it contains iron, its crystal color is often blue-green, yellow-green or light green, with varying colors. The better quality CuSO4.5H2O can be used as a reference for observation.
    Industrial Grade Copper Sulfate Pentahydrate quality appraisal and other more methods and testing methods, interested can contact our company. In addition to the content and other indicators of copper sulfate in the electroplating industry, detailed testing of heavy metals and other indicators is also required. In fact, choosing a brand is the most worry-free, and this is also the simplest and most effective method.
