If NaNO3 is cooled from 70C to 10C ; how much solid NaNO3 will come out of solution as a solid salt?
Help me !!!
To determine how much solid NaNO3 will come out of the solution when it is cooled, we need to consider the solubility of NaNO3 at different temperatures.
The solubility of a substance typically increases with temperature, meaning that more of it can dissolve in a solution at higher temperatures. Conversely, as temperature decreases, the solubility decreases, resulting in the formation of solid particles.
To find the amount of NaNO3 that will come out of the solution, we need to compare the solubility of NaNO3 at the initial temperature of 70°C and the final temperature of 10°C.
Here's how you can find the answer:
1. Determine the solubility of NaNO3 at 70°C: You can consult a solubility chart or look up the solubility of NaNO3 at 70°C. Let's say the solubility is x grams per 100 grams of water.
2. Determine the solubility of NaNO3 at 10°C: Again, consult a solubility chart or look up the solubility of NaNO3 at 10°C. Let's say the solubility is y grams per 100 grams of water.
3. Calculate the difference in solubility: Subtract the solubility at 10°C (y) from the solubility at 70°C (x). The difference, x - y, represents the amount of NaNO3 that will crystallize out of the solution.
For example, if the solubility of NaNO3 at 70°C is 80 grams per 100 grams of water and the solubility at 10°C is 30 grams per 100 grams of water, the difference in solubility would be:
80 g/100g - 30 g/100g = 50 g/100g
This means that 50 grams of NaNO3 will come out of the solution as solid salt when cooled from 70°C to 10°C.
Remember to adjust the units of measurement as needed, and consult reliable sources for accurate solubility data.
