Okay there is a question in my book, but go figure it's one that doesn't have the answer in the back of the book for me to check my answer.
it says predict the effect each change has on the solubility of (1)Na2CO3(s); (2)N2(g)
a. increase in temperature
b. decrease in temperature
c. increase in pressure
d. decrease in pressure
After reading the laws this is what I have figured
a. N2 solubility decreases, Na2CO3 solubility increases
b. N2 solubility Increases, Na2Co3 solubility decreases and precipitates
c. N2 solubility increases, Na2CO3 (I'm not sure)
d. N2 solubility decreases, Na2CO2 (I'm not sure)
Can you help?
Thanks
I could help if I knew the question. Solubility Na2CO3 in what? Solubility N2 in what? If in water then your answers are correct. For c and d on solubility Na2CO3 for increase and decrease in pressure, there is essentially no change. Liquids and solids don't change much with changing pressure.
Of course! I'd be happy to help you with your question.
To determine the effect of each change on the solubility of Na2CO3 and N2, we need to consider the factors that influence solubility: temperature, pressure, and the nature of the solute and solvent.
For Na2CO3(s), let's analyze each change:
a. Increase in temperature: Generally, solubility of solid solutes tends to increase with an increase in temperature. Therefore, it is likely that the solubility of Na2CO3(s) would also increase when the temperature is increased.
b. Decrease in temperature: The solubility of most solid solutes decreases as temperature decreases. Therefore, it is likely that the solubility of Na2CO3(s) would also decrease when the temperature is decreased. In this case, it can potentially precipitate out of the solution.
c. Increase in pressure: Changes in pressure only have a significant effect on the solubility of gases, not solid solutes like Na2CO3. Therefore, the change in pressure should have no effect on the solubility of Na2CO3(s).
d. Decrease in pressure: Similarly, the change in pressure should have no effect on the solubility of Na2CO3(s) since it is a solid solute.
Now, let's consider the effect of each change on the solubility of N2(g):
a. Increase in temperature: According to Henry's Law, the solubility of gases generally decreases as temperature increases. Therefore, it is likely that the solubility of N2(g) would decrease when the temperature is increased.
b. Decrease in temperature: The solubility of gases tends to increase as the temperature decreases. Hence, it is likely that the solubility of N2(g) would increase when the temperature is decreased.
c. Increase in pressure: The solubility of gases generally increases as the pressure increases. Therefore, it is likely that the solubility of N2(g) would increase when the pressure is increased.
d. Decrease in pressure: Decreasing the pressure would decrease the solubility of gases. Thus, it is likely that the solubility of N2(g) would decrease when the pressure is decreased.
So, to summarize the effects of each change on the solubility:
Na2CO3(s):
a. Increase in temperature: Solubility increases.
b. Decrease in temperature: Solubility decreases, potentially precipitates.
c. Increase in pressure: No significant effect.
d. Decrease in pressure: No significant effect.
N2(g):
a. Increase in temperature: Solubility decreases.
b. Decrease in temperature: Solubility increases.
c. Increase in pressure: Solubility increases.
d. Decrease in pressure: Solubility decreases.
I hope this explanation helps! If you have any more questions, feel free to ask.
Sure, I'd be happy to help you with this question. Based on the given changes, here are the effects on the solubility of Na2CO3(s) and N2(g):
a. Increase in temperature:
- Na2CO3 solubility: Na2CO3 is an ionic compound. In general, the solubility of ionic compounds increases with an increase in temperature. Therefore, the solubility of Na2CO3 will increase when the temperature is increased.
- N2 solubility: N2 is a nonpolar gas and it is not very soluble in water. So, the solubility of N2 will be largely unaffected by an increase in temperature.
b. Decrease in temperature:
- Na2CO3 solubility: As mentioned earlier, the solubility of most ionic compounds increases with an increase in temperature. Therefore, the solubility of Na2CO3 will decrease when the temperature is decreased.
- N2 solubility: N2 is not very soluble in water and its solubility is generally not affected by changes in temperature. So, the solubility of N2 will be largely unchanged by a decrease in temperature.
c. Increase in pressure:
- Na2CO3 solubility: Increasing the pressure has no significant effect on the solubility of ionic compounds like Na2CO3.
- N2 solubility: N2 is a nonpolar gas and its solubility in water is mainly determined by temperature rather than pressure. Therefore, increasing the pressure will not have a significant effect on the solubility of N2.
d. Decrease in pressure:
- Na2CO3 solubility: Decreasing the pressure has no significant effect on the solubility of Na2CO3.
- N2 solubility: Similarly, decreasing the pressure will not have a significant effect on the solubility of N2.
So, to summarize:
a. Increase in temperature: Na2CO3 solubility increases, N2 solubility remains largely unchanged.
b. Decrease in temperature: Na2CO3 solubility decreases, N2 solubility remains largely unchanged.
c. Increase in pressure: No significant effect on the solubility of both Na2CO3 and N2.
d. Decrease in pressure: No significant effect on the solubility of both Na2CO3 and N2.
I hope this helps! Let me know if you have any further questions.
