What is the solute and solvent of 5% Benzaldehyde solution?
Q. What is the solute and solvent of 5% Benzaldehyde solution?
Asked by choco - Wed Mar 4 07:53:56 2009 - - 2 Answers - 0 Comments
A. I began to answer this question earlier and gave up. Unfortunately benzaldehyde does not dissolve sufficiently in water to enable you to make a solution 5g benzaldehyde and 95g water. I did not proceed further because I could not find a solvent for benzaldehyde, except possibly an ethylene glycol. However if you want a general answer, the 5% (5g) benzaldehyde would be the solute and the 95%(95g) solvent (whatever it is), would be the solvent

Two liquids combined in same proportion, which is solvent and solute?
Q. When a 10mL portion of isopropyl alcohol(a liquid) and a 10mL of water are combined, the resulting mixture is a solution. What is the water called in this mixture? a. Solute b. Solvent c. Solution d. None of the above
Asked by vin917 - Fri Feb 1 16:06:30 2008 - - 5 Answers - 0 Comments
A. The solvent, because it is denser than IPA (isopropyl alcohol)and thus there is more mass of water there when you add equal volumes.. Also, if you look at it from the direction of which one has more moles present, water has a lower molecular weight, so there are more moles of it present. Water MW is 17 grams/mole; IPA MW is 60 grams/mole. Either way, water is the solvent.

Is it good practice to add the solute to the solvent instead of vice versa?
Q. Why not add the solute first, then the solvent? Wouldn't the solute go into solution faster that way? I'm aware that when dealing with acid dilutions, the acid should be added to the water, because otherwise the high initial acid concentrations can cause extreme heat and sometimes explosions (when dealing with certain acids). But apart from that (and apart from any other dangerous reactions), is there any general rule which governs reagent addition order?

A. As you mentioned it is true in case of acids.. Add Acids to water but not the other way... (AA---Add Acid) To my knowledge there is no particular convention for solute to dissolve in solvent. Except fo hygroscopic solutes( absorbs atmospheric water), for which it is better to take them first and add water (since it will absorb water, it may effect the final volume if you mix vice versa. Except for hygroscopic solutes, theres no particular convention is this info helpful?

Q. Example in kool-aid, is the powder the solute or solvent?
Asked by bihacmi - Sun Nov 9 19:50:36 2008 - - 1 Answers - 0 Comments
A. "The thing added" is ambiguous. You can add the powder to the water, or the water to the powder (depending on which enters the container first.) The dissolving medium is the solvent. In a solution containing a solid and a liquid, the liquid is always considered to be the solvent. (Liquids have priority over solids, which have priority over gases. When a solution consists of more than one component of the same state, the one present in greatest quantity is considered to be the solvent.)

A. I believe the rule is "like dissolves like". Non-polar solutes dissolve in non-polar solvents and polar solutes dissolve in polar solvents. As an example, oil (consisting of non-polar C-H bonds) won't easily dissolve in water (strongly polar due to the O-H bonds), but water easily dissolves most alcohols (ethanol for example, C2 H5 OH) because of the polar OH group.
