A Saturated Solution Of Barium Chloride Is At 20°C And Contains 150 Grams Of Water. How Much More Barium Chloride Can Be Added To The Solution If Its Temperature Is Raised To 80°C?
Introduction
A saturated solution is a chemical solution containing the maximum concentration of a solute dissolved in the solvent. In this case, we have a saturated solution of barium chloride (BaCl2) at 20°C, containing 150 grams of water. The solubility of barium chloride in water is a function of temperature, and we need to determine how much more barium chloride can be added to the solution if its temperature is raised to 80°C.
Solubility of Barium Chloride
The solubility of barium chloride in water is given by the following equation:
BaCl2 (s) ⇌ Ba2+ (aq) + 2Cl- (aq)
The solubility of barium chloride in water is 2.18 g/100 mL at 20°C and 4.03 g/100 mL at 80°C. This means that for every 100 mL of water, 2.18 g of barium chloride can be dissolved at 20°C, and 4.03 g of barium chloride can be dissolved at 80°C.
Calculating the Initial Amount of Barium Chloride
To calculate the initial amount of barium chloride in the solution, we need to know the mass of the solution and the mass of the water. We are given that the solution contains 150 grams of water. The mass of the solution is equal to the mass of the water plus the mass of the barium chloride.
Let's assume that the mass of the barium chloride is x grams. Then, the mass of the solution is:
m_solution = m_water + m_BaCl2 = 150 g + x g
The volume of the solution is equal to the volume of the water, which is 100 mL. The density of the solution is equal to the density of the water, which is 1 g/mL.
The solubility of barium chloride in water at 20°C is 2.18 g/100 mL. Therefore, the initial amount of barium chloride in the solution is:
m_BaCl2_initial = (2.18 g/100 mL) × (100 mL) = 2.18 g
Calculating the Final Amount of Barium Chloride
When the temperature of the solution is raised to 80°C, the solubility of barium chloride increases to 4.03 g/100 mL. The volume of the solution remains the same, 100 mL. Therefore, the final amount of barium chloride in the solution is:
m_BaCl2_final = (4.03 g/100 mL) × (100 mL) = 4.03 g
Calculating the Amount of Barium Chloride that Can be Added
To calculate the amount of barium chloride that can be added to the solution, we need to subtract the initial amount of barium chloride from the final amount of barium chloride:
m_BaCl2_added = m_BaCl2_final - m_BaCl2_initial = 4.03 g - 2.18 g = 1.85 g
Therefore, 1.85 grams of barium chloride can be added to the solution when its temperature is raised to 80°C.
Conclusion
In conclusion, the solubility of barium chloride in water is a function of temperature. When the temperature of a saturated solution of barium chloride is raised from 20°C to 80°C, the solubility of barium chloride increases from 2.18 g/100 mL to 4.03 g/100 mL. Therefore, 1.85 grams of barium chloride can be added to the solution when its temperature is raised to 80°C.
