It would take 100,000 liters of water to dilute 1 liter of copper chlorine solution.
100k
By (internal) auto-redox reaction 'bleach' is formed: Cl2 + 2NaOH --> NaClO + NaCl
To dilute it.
If the solute isn't very soluble, the solution can be saturated and still have very little solute in it, so it would be dilute.
Yes, ammonia is poisonous to humans, but only in large quantity. When ammonia is used as a dilute solution in water (as a cleaning agent, for example) it is not dangerous. Pure ammonia is approximately as toxic as chlorine gas.
How to prepare 0,28% ammonia
You would need 999,999L of water to dilute used copper chloride solution
An electrolysis process is based upon movement and flow of ions. More is the solution dilute, more is the movement of ions and more is the conductance of solution. Thus, when the solution is dilute more copper ions flow to the electrode and get deposited there
They cannot survive in a 100% pure chlorine solution. However, for a very brief period they may survive in an extremely dilute chlorine solution.
Chlorine will displace bromine from NaBr
When dilute sulfuric acid reacts with copper(II) carbonate, blue copper(II) sulfate solution is produced.
Blue
Mixing these two reagents would make a dilute solution of copper sulfate.
Copper Carbonate
You will get a solution of potassium chloride and potassium hypochlorite.
Probably a very dilute solution of copper sulphate act as a desinfecting agent; but the copper sulphate is toxic. It is more sure to avoid this experiment.
The dilute solution become a concentrated solution.
Copper does not react with dilute Sulphuric acid.
