Without the salt step, if you compounds do not react in stoichiometric proportions, chain termination can occur too quickly and limit molecular weight.
Salt is an element that is composed of sodium and chlorine ions. Iron is also an element, with the chemical symbol Fe. Nylon is not an element, but rather a synthetic polymer made from repeating units of monomers.
Exactly the same amount of salt as you weighed out to make the salt water solution in the first place.
People who make salt are called salt producers or salt miners. They are responsible for extracting salt from salt mines or evaporating salt water to produce salt for consumption and various other purposes.
Table salt.
To make a 3000 ppm salt solution, first determine the amount of salt needed. Since ppm (parts per million) is equivalent to milligrams of solute per liter of solution, you would need 3000 mg of salt for every 1 liter of water. Measure out 3000 mg of salt (e.g., sodium chloride) and dissolve it in enough water to make the total volume 1 liter. Stir the solution until the salt is completely dissolved.
Salt is water soluble, use that to your advantage. You should be able to wash the salt off just by rinsing it. Hot water will dissolve the salt faster, but make sure it isn't so hot that is melts the nylon.
To remove salt stains from nylon boots, mix a solution of equal parts water and vinegar. Dip a soft cloth into the solution and gently wipe the salt stains off the boots. Allow the boots to air dry completely before use.
Salt is an element that is composed of sodium and chlorine ions. Iron is also an element, with the chemical symbol Fe. Nylon is not an element, but rather a synthetic polymer made from repeating units of monomers.
Nylon is made through a process called polycondensation, primarily involving the reaction of diamines with dicarboxylic acids or their derivatives. The steps typically include: 1) reacting hexamethylenediamine with adipic acid to form a salt; 2) heating this salt to initiate polymerization, which produces the nylon polymer; 3) extruding the polymer into fibers; and 4) cooling and stretching the fibers to enhance their strength and elasticity. The resulting nylon can then be spun into textiles or used in various applications.

First you must dip the rock in the water(hot) and that will make the salt and water into a mixture...this makes salt wateruse simple evapuration to separate the salt from the water!Hope i helped!!
Nylon is one of the most important chemical discoveries of the 20th century .It is one of the toughest , strongest and most elastic substances we have today . It is a synthetic plastic material which is made from chemicals derived from coal, water, air, petroleum, agricultural by-products and natural gas . It was first developed by a research team headed by a U.S. chemist Wallace H.Corothers working in E.l. Dupant De Nemours & Co. He began experimenting with it in the 1920s. In 1935, he produced the first piece of nylon. It was converted into cloth in 1937. Nylon is made from two chemical compounds : Hexamethylenediamine consists of carbon, nitrogen and hydrogen. Adipic acid contains carbon, hydrogen and oxygen. Each of these substances contains six carbon atoms and the Nylon-6, 6. Manufacturers combine the two compounds to form a substance called nylon salt. A solution of nylon salt is placed in an autoclave (a heating device). The autoclave heats the solution under pressure. Water is removed and the small molecules in the compound , combine to form large molecules. This process is called polymerisation. When caprolactam is used as the starting material, Nylon -6, 6 is obtained. It has been so named because it has six carbon atoms in the basic unit. It is comparatively a recent development.
you make salt water denser by putting more water or taking the salt off the salt water!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
To make crystals using salt and vinegar, first dissolve salt in vinegar to create a saturated solution. Then, allow the solution to evaporate slowly in a container. As the liquid evaporates, salt crystals will form. You can also try adding food coloring to create colored crystals.

Salt will melt first.
