Meanwhile, the metal clad here is 24K gold also added as an anode (anode). When an electric current is passed through a wire connecting the two electrodes, the gold ions at the positive pole will move to the cathode, the rose that needs to be plated, clinging to the surface. At the end of the electroplating process, we will get a complete gold-plated rose.

Not only stop at the gold inlaid gold roses, many people also invest in making rose or orchids in gold.

However, if you want to know what is a fake gold rose, you can proceed to the following chemical experiment:

First remove a portion of the washed rose and put it in a test tube containing distilled water. Add the tube of nitric acid solution (HNO ₃ ) and heat to remove the metals mixed in it.

Rinse the yellow flower that has not yet melted and dissolve it into a hydrophobic water solution (a mixture of HCl hydrochloric acid and nitric HNO ₃ with a ratio of 3: 1) - the water can dissolve gold.

Heat the solution until the acid evaporates and use up to 2 sheets of impregnated filter paper tirava gold solution. Small solution containing melted rose gold into a filter paper. Next, put the real gold solution on another sheet of paper and compare. Filter paper containing real gold will produce a light brown precipitate while false gold does not occur.
