If by "salt" you mean sodium chloride, then YES, it is most definitely soluble.
Adding water to salt, is not increasing solubility, it is increasing the ammount of solvent, and thereby increasing the ammount of salt in solution :).
A stirred supersaturated solution can be considered as a suspension.
the temperature of the water (table G in the chemistry reference table)
You reach the solubility of salt in water when the salt stops dissolving and settles at the bottom, no matter how hard you try to mix it. You can increase solubility by increasing the water temperature.
Salt in water is an example of solubility.
In presence of salt the crystals grow faster because the solubility of salt decreases the solubility of any other compound in water.
The solubility of salt in water increases with higher temperatures.
Salt dissolves more easily than sugar, in my experience. But the solubility is similar. :)
The volume solution in conical flask is very important in solubility ionic salt water. This is because it determines its solubility.
Solubilization of salt in water is a physical change.
By stirring, heating, or adding more water :)
Ammonium chloride has the greatest solubility in water at 25 degrees Celsius, with a solubility of 37.2g/100mL of water.
