要由铜制备水合硫酸铜(II)晶体，首先把铜在空气中加热，生成黑色的氧化铜(II)固体。 2Cu(s) + O2(g) → 2CuO(s) 然后，逐少把氧化铜(II)加入一定体积的稀硫酸中，并把混合物轻微加热，直至氧化铜(II) 不能溶为止。形成的溶液是硫酸铜(II)溶液。 CuO(s) + H2SO4(aq) → CuSO4(aq) + H2O(l) 把混合物过滤，除去过量的氧化铜(II)固体。把蓝色滤液（硫酸铜(II)溶液）加热，除去部份溶剂 (水)，形成热的浓溶液（甚至饱和溶液）。然后把溶液缓慢地冷却，会析出水合硫酸铜(II) (CuSO4•5H2O) 的晶体。把混合物过滤，然后把残余物硫酸铜(II)晶体以少量冰冻乙醇冲洗，然后放在 80oC 的焗炉中焗干。 （当水合硫酸铜(II)的晶体在水溶液中形成时，水合过程会自然进行，无需任何特别的步骤。） ========== 铜与稀硫酸没有反应。 虽然铜与热的浓硫酸会反应，形成硫酸铜(II)溶液，但因为溶液中含有浓硫酸，难以处理，所以不会采用为制备硫酸铜(II)晶体的方法。
Since it is available mercially
copper sulfate is usually purchased
not prepared in the laboratory. It can be made by the action of sulfuric acid on a variety of copper(II) pounds
for example copper(II) oxide. Copper(II) sulfate deposes before melting. The mon pentahydrate form dehydrates
losing four water molecules at 110 °C and all five at 150 °C. At 650 °C
copper(II) sulfate deposes into copper(II) oxide (CuO) and sulfur trioxide (SO3). When heated in an open flame the crystals are dehydrated and turn grayish-white
