1. Removal of nitric acid: Add urea until no more visible reaction (fizzing stops)
2. Precipitation of Gold: Add ferrous sulfate. This causes the gold chloride to "reduce" to gold, yielding a cloudy solution ready for filtering.
3. Filtration: Allow precipitation to occur for as long as possible (1 night here). Siphon and filter gold. Clean and cast.
Answer
Not very easily! I don't know of any ways... Presumably you'd want to either use a precipitation reaction or an electrochemical method, but in both cases I don't know of any reagents that wouldn't get destroyed by the aqua regia themselves in the process.
Answer
Or you can just place a piece of metal higher in the reactivity series than gold (that's just about every metal) in the solution and the gold will come out.
The easiest way to get dissolved solids back is to let the water evaporate.
Add chlorine
evaporate the water
Ammonium hydroxide (NH4OH) is a common, though not entirely correct name for a solution of ammonia dissolved in water.when dissolved in water ammonia reacts to a small degree with water to produce ammonium hydroxide (NH3 + H2O --> NH4OH). But this only forms in a small amount and most of the ammonia remains unreacted. This substance cannot be isolated as any attempt to separate it out will result in it reverting back to ammonia and water.its the state that daisy go into after an animal has urinated on it
When common sugar (Sucrose) is dissolved in water it is converted into two units ,Glucose and Fructose so you Can not get back same sugar from water.
The easiest way to get dissolved solids back is to let the water evaporate.
By evaporating the water out, which precipitates the sugar back into its crystalline form.

Put them in water. Sugar dissolves, sand remains Filter the solution to separate sand and salt. Evaporate solution with dissolved salt to get salt back
Go to slateport city and visit the crowd then come back and visit the aqua base.
no you can not get back in to their base trust me i tried
Dissolve it it water and filter it through paper. The sand will be in the paper and then sugar will be dissolved in the water. You can let the water evaporate and you will have the sugar back.
No they don't grow back they just get lost
you deliver it to captn.stern
in the back of the base, but they get away with it.
It represents a laid back and easy-going
