The solubility point of salt is the limit where no more salt can dissolve in water. If you keep adding salt after this point, it will stay undissolved or form solid pieces again. At room temperature, you need about six teaspoons of salt in 100 millilitres of water to reach this limit.
The temperature of the water is the determining factor. The rate of salt dissolution is accelerated by warmer water. The reason for this is that more kinetic energy is possessed by the water molecules in hot water. This enables them to disassemble the salt crystals. For water at room temperature, the recommended amount is 7-9 teaspoons. An experiment could be conducted to determine the truth.
