30g of Nacl saturates 15g of water at 10^0c calculate the solubility of Cacl2 at that temperature in g/100g of solvent
Thanks
Can't calculate solubility of CaCl2 from NaCl data.
To calculate the solubility of CaCl2 at a given temperature, we need to find the amount of CaCl2 that can dissolve in 100g of water at that temperature. The given information about NaCl solubility can be used to determine the solubility of CaCl2 using the principle of solubility ratio.
The solubility ratio states that the solubility of one substance is proportional to the solubility of another substance at the same temperature. This means that the ratio of the solubilities of two substances at a given temperature remains constant.
We can use this principle to find the solubility of CaCl2.
Given:
Mass of NaCl = 30g
Mass of water = 15g
Temperature = 10^0C
1. Determine the solubility of NaCl at the given temperature:
Using the given information, we know that 30g of NaCl saturates 15g of water at 10^0C. This means that the solubility of NaCl is 30g/15g or 2g/g (grams of NaCl per gram of water).
2. Use the solubility ratio to find the solubility of CaCl2:
Since the solubility ratio is constant at a given temperature, we can use it to find the solubility of CaCl2. Let's assume the solubility of CaCl2 is x g/100g of water.
From step 1, we know that the solubility of NaCl is 2g/g. Therefore, the solubility ratio of CaCl2 to NaCl is:
x g/100g CaCl2 / 2g/g NaCl = x/2 g/100g CaCl2 per g NaCl
Now, we need to set up a proportion to solve for x:
x/2 = 15/30
Cross-multiply and solve for x:
x = (2 * 15) / 30
x = 1g/100g
Therefore, the solubility of CaCl2 at 10^0C is 1g/100g of water.
So, the answer is:
The solubility of CaCl2 at 10^0C is 1g/100g of solvent.
