Ksp of a CaSO4.5H2O is 9x10^-6. Find volume of CaSO4 for 1gm.(Mw = 136...
Calculation of Volume of CaSO4 for 1gm
- Given: Ksp of CaSO4.5H2O = 9x10^-6, Molar weight (Mw) of CaSO4 = 136 g/mol
Step 1: Calculate the molar solubility of CaSO4 in water
- The molar solubility of CaSO4 can be calculated using the Ksp value:
- CaSO4.5H2O → Ca2+ + SO4^2- + 5H2O
- Ksp = [Ca2+] [SO4^2-] = 9x10^-6
- Since CaSO4 dissociates into Ca2+ and SO4^2- ions in a 1:1 ratio:
- Let x be the molar solubility of CaSO4, then:
- Ksp = x * x = x^2 = 9x10^-6
- x = √(9x10^-6) = 3x10^-3 mol/L
Step 2: Calculate the volume of CaSO4 for 1gm
- 1 gram of CaSO4 is equivalent to 1/136 mol (since Mw = 136 g/mol)
- Volume = Number of moles / Molarity
- Volume = (1/136) / (3x10^-3) = 25.45 L
Therefore, the volume of CaSO4 required for 1gm is approximately 2.45 litres.
Final Answer: A) 2.45 litre
- Given: Ksp of CaSO4.5H2O = 9x10^-6, Molar weight (Mw) of CaSO4 = 136 g/mol
Step 1: Calculate the molar solubility of CaSO4 in water
- The molar solubility of CaSO4 can be calculated using the Ksp value:
- CaSO4.5H2O → Ca2+ + SO4^2- + 5H2O
- Ksp = [Ca2+] [SO4^2-] = 9x10^-6
- Since CaSO4 dissociates into Ca2+ and SO4^2- ions in a 1:1 ratio:
- Let x be the molar solubility of CaSO4, then:
- Ksp = x * x = x^2 = 9x10^-6
- x = √(9x10^-6) = 3x10^-3 mol/L
Step 2: Calculate the volume of CaSO4 for 1gm
- 1 gram of CaSO4 is equivalent to 1/136 mol (since Mw = 136 g/mol)
- Volume = Number of moles / Molarity
- Volume = (1/136) / (3x10^-3) = 25.45 L
Therefore, the volume of CaSO4 required for 1gm is approximately 2.45 litres.
Final Answer: A) 2.45 litre
