I am pretty confused on this.
1. Pick the appropriate solvent to dissolve
A) Sodium Chloride (ionic)
B) Sodium Nitrate (ionic)
both have the choices of
1) water
2) acetone
3)ethanol
4)methanol
5)carbon tetrachloride
6)toluene
7)hexane
I got it. Both have the same answers of water, methanol, ethanol and acetone!
Both are ionic therefore both are polar bonds and would dissolve in a polar solvent like H2O.
I would expect both to be somewhat soluble in methanol and ethanol. They are polar but not as much as H2O.
I know they are somewhat polar but the program im using is confusing me.
for A) on the first attempt i answered just water
second attempt methanol and water and the third attempt water methanol and ethanol
all come back incorrect.
for B) on the first attempt i tried just water and on the second attempt water, ethanol and methanol.
i don't understand where im going wrong here
If that's all there is the the question, I would answer water for both. There may be more to the question than that. "Appropriate" could be the ringer word. Have you summarized the question or is this all there is?
that's all there is unfortunately. answering just water for both gave me incorrect feedback.
I don't like the question. It's too vague. For ALL of the answers it should have been quoted as something like this. "What solvents will dissolve NaCl and NaNO3?"
To ask what is the APPROPRIATE solvent makes one wonder appropriate for what? Thanks for letting me know.
To pick the appropriate solvent to dissolve sodium chloride (ionic) and sodium nitrate (ionic), you need to consider the solubility of these compounds in different solvents. Solubility refers to the ability of a substance to dissolve in a particular solvent.
The solubility of sodium chloride and sodium nitrate can be determined by referring to solubility tables or solubility rules. In this case, both compounds are highly soluble in water. Sodium chloride is also slightly soluble in methanol and ethanol.
Let's go through the options one by one:
1) Water: Both sodium chloride and sodium nitrate are highly soluble in water. Therefore, water would be an appropriate solvent for dissolving both compounds.
2) Acetone: Sodium chloride is not significantly soluble in acetone, while sodium nitrate is slightly soluble in acetone. So, acetone may not be the best choice for dissolving sodium chloride but can dissolve sodium nitrate to some extent.
3) Ethanol: Sodium chloride is slightly soluble in ethanol, while sodium nitrate is highly soluble in ethanol. Therefore, ethanol can be used as a solvent for both compounds.
4) Methanol: Sodium chloride is slightly soluble in methanol, whereas sodium nitrate is highly soluble in methanol. So, methanol would be appropriate for dissolving both compounds.
5) Carbon Tetrachloride: Both sodium chloride and sodium nitrate are not significantly soluble in carbon tetrachloride. Therefore, it is not a suitable solvent for either compound.
6) Toluene: Both sodium chloride and sodium nitrate are not significantly soluble in toluene. Therefore, toluene is not an appropriate choice for dissolving either compound.
7) Hexane: Both sodium chloride and sodium nitrate are not significantly soluble in hexane. Hence, hexane is not suitable as a solvent for either compound.
In summary, the solvents that can dissolve both sodium chloride and sodium nitrate are:
1) Water
2) Ethanol
3) Methanol
It's important to note that the solubility of compounds can also depend on temperature, so the solubility information provided here may apply at room temperature or a specific temperature mentioned in the question.
