36 gm of sodium chloride should be dissolved in 100 gm of water at 293 K temperature to make a saturated solution. The concentration at this temperature is 26.47%. Mass percent is the method of indicating the concentration or explaining a part of a particular mixture. The solution composition can be expressed as a mass percent. It indicates the solute present in a given solution mass. Solute values are expressed in mass or moles. For solutions, the mass percent is shown as grams of solute per gram of solution and is multiplied by 100 to get the percentage.

Effects of Temperature

  • The solubility increases with the increase in temperature
  • The solubility decreases with a decrease in temperature

Steps to Calculate the Concentration at Temperature

Step I: Determine the total mass of the solution:

water mass (H2O as solvent) = 100 gm

sodium chloride mass (NaCl as solute) = 36 gm

solution mass = 36 + 100 = 136 gm

Step II: Determine the concentration:

Concentration = (mass of a solute/ mass of a solution) x 100

= 36/136 x 100

= 26.47%

Uses of sodium chloride

  • It is widely used in the food industry as a preservative and flavor enhancer.
  • It is an important raw material in the industrial production of various chemicals such as sodium carbonate, sodium bicarbonate.
  • This salt is used in the manufacture of glass.
  • Used in cold countries to protect roads, bridges, etc. from freezing. This is important for safe driving conditions.

Summary:

To make a saturated solution, 36 gm of sodium chloride is dissolved in 100 gm of water at 293 K. Find its concentration at this temperature.

To prepare a saturated solution, 36 gm of sodium chloride has to be dissolved in 100 gm of water at a temperature of 293 K. The concentration is 26.47% at this temperature.
