a saturated solution of barium chloride at 30C contains 150g water. How much additional barium chloride can be dissolved by heating this solution to 60C?

Surely you have a graph or a table that gives you the solubility of BaCl2 at various temperatures. I don't have the solubility of all of the salts at different temperatures memorized.

To determine how much additional barium chloride can be dissolved by heating the solution, we need to compare the solubility of barium chloride at 30°C and 60°C.

First, let's calculate the solubility of barium chloride at 30°C. The given information tells us that the saturated solution contains 150g of water. However, we need to know the solubility of barium chloride, not the amount of water. So, we need to find the solubility at 30°C.

Next, we'll determine the solubility of barium chloride at 60°C. We'll use the solubility values to figure out how much additional barium chloride can be dissolved in the heated solution.

To find the solubility at each temperature, we'll need to look up the solubility of barium chloride in water at those specific temperatures. The solubility values for barium chloride are typically given in grams per 100g of water.

Once we have the solubility at each temperature, we'll calculate how much additional barium chloride can be dissolved by subtracting the initial solubility (at 30°C) from the solubility at 60°C.

Here's how you can find the solubility values and calculate the additional amount:

1. Look up the solubility of barium chloride at 30°C. Let's say the solubility is X grams per 100g of water.

2. Divide the given amount of water (150g) by 100 and multiply it by the solubility value to find the initial amount of barium chloride dissolved at 30°C.

Initial amount of barium chloride dissolved = (150g/100) * X

3. Look up the solubility of barium chloride at 60°C. Let's say the solubility is Y grams per 100g of water.

4. Divide the given amount of water (150g) by 100 and multiply it by the solubility value to find the amount of barium chloride dissolved at 60°C.

Amount of barium chloride dissolved at 60°C = (150g/100) * Y

5. Calculate the additional amount of barium chloride that can be dissolved by subtracting the initial amount from the amount at 60°C.

Additional amount of barium chloride dissolved = Amount at 60°C - Initial amount

By following these steps, you'll be able to find the additional amount of barium chloride that can be dissolved by heating the solution to 60°C.
