a. The solubility of barium iodate monohydrate in 25°C water is 0.028 g per 100. mL of water. Calculate the solubility, or in other words, the proportion of how much product would dissolve if you rinsed it with 125 mL of 25°C distilled water. b. Suppose you have 4.832 g of product and then rinse it with 125 mL of 25°C water, use the answer in 2a to calculate how much product would you expect to isolate. c. The solubility of barium iodate monohydrate in 4°C water is 0.010 g per 100 mL of water. Calculate the solubility, or in other words, how much product would dissolve if you rinsed it with 20.0 mL of 4°C distilled water.

Question
Name: Section POST-LAB QUESTIONS continued 2. Assume that, in the experiment described in Question 2, 125 mL of 25°C distilled water was used to wash and transfer the precipitate, rather than 20. mL of chilled distilled water (at 4°C). a. The solubility of barium iodate monohydrate in 25°C water is 0.028 g per 100. mL of water. Calculate the solubility, or in other words, the proportion of how much product would dissolve if you rinsed it with 125 mL of 25°C distilled water. b. Suppose you have 4.832 g of product and then rinse it with 125 mL of 25°C water, use the answer in 2a to calculate how much product would you expect to isolate. c. The solubility of barium iodate monohydrate in 4°C water is 0.010 g per 100 mL of water. Calculate the solubility, or in other words, how much product would dissolve if you rinsed it with 20.0 mL of 4°C distilled water. d. Suppose you have 4.832 g of product and then rinse it with 20.0 mL of 4°C water, use the answer in 2c to calculate how much product would you expect to isolate. e. Using your answers from (b) and (d), calculate the percent error or percent difference as a result of accidentally using the 25°C water, water that is too warm, compared with the correct (accepted) yield isolated using 20. mL of 4°C water.
