Can you separet gold from aqua regia with k2s2o5?
Yes, it is possible to separate gold from aqua regia using potassium disulfite (K2S2O5). When K2S2O5 is added to aqua regia, it can reduce gold ions back to metallic gold, precipitating it out of solution. This process is often used in gold refining to recover gold from the aqua regia solution after it has dissolved the metal. However, proper safety precautions should be taken, as aqua regia is highly corrosive and toxic.
