The action of salt water on copper is not important: see also the link below.
Salt water and table salt +water are the same thing- a solution. Aluminum, gold and iron are all elements (pure substances) and can not be broken down. Jello is a colloid. Muddy water is a suspension, plus salad dressing. Perhaps sugar could be called a pure substance. But it can be broken down into its' component parts. Tea also.

The amount of salt water you get will depend on the concentration of salt in the water. When you mix salt with water, the salt dissolves into the water to increase its volume slightly. The overall volume of the salt water will be the sum of the volumes of the original salt and water components.
salt is not from salt water
To make salt water, simply dissolve salt in water until no more salt can be dissolved. The ratio is typically about 1 cup of salt per gallon of water. Stir the mixture until the salt is completely dissolved. You now have salt water ready for use.

Mix with water, the pass through a filter paper. The salt will be dissolved in the water so it will be removed with the water, leaving the iron filings and gold dust on the filter paper. Leave this to dry then separate off the iron filings using a magnet, leaving behind the gold.
Sodium can be separated into simpler substances only by chemical means. Water, salt, and gold are pure substances that cannot be separated into simpler substances by chemical means.
gold fish is what I think.
Salt can be separated from water by evaporation. When water is heated, it evaporates and leaves the salt behind. Another method is distillation, where the saltwater is heated, and the steam is collected and condensed back into liquid water, leaving the salt behind.
in ancient Ghana salt was more valuable. gold was everywhere whereas salt was rare. also salt was more valuable because salt helps you retain water which ment they could travel longer without water, increasing trade across the Sahara desert. also salt helped preserve food, making it worth more than gold
Salt hasn't gold.
Yes, they did trade there gold for salt.
Most metals, and especially gold. AND SALT WATER
Sugar and salt are compounds because they are made up of two or more elements chemically bonded together. Gold, on the other hand, is a pure element since it is made up of only gold atoms. Water is also a compound because it is made up of hydrogen and oxygen atoms bonded together.
A sugar is a compound that consists of carbon, hydrogen, and oxygen atoms. Salt is a compound composed of sodium and chloride ions. Gold is a chemical element and not a compound. Water is a compound composed of hydrogen and oxygen atoms.
