What else can I help you with?
How would you expect Rf values to change if you went from hexane-ethyl acetate solvent system to ethyl acetate only?
If you switch from a hexane-ethyl acetate solvent system to ethyl acetate only, you would expect the Rf values to decrease. Ethyl acetate is a more polar solvent than hexane, so compounds will interact more with the solvent and have shorter distances of travel on the TLC plate, resulting in lower Rf values.
Does barium acetate and lithium sulfate form a precipitate?
Yes, when barium acetate and lithium sulfate are mixed, a white precipitate of barium sulfate would form due to a double displacement reaction. This is because barium sulfate is insoluble in water.
Is silver a solvent or solute?
Silver is a solute, not a solvent. A solute is the substance that is dissolved in a solution, while a solvent is the substance that does the dissolving. In the case of silver being dissolved in a solution, it would be considered the solute.
What solvent system would give the highest Rf value for acetophenone?
A non-polar solvent system, such as hexanes and ethyl acetate, would provide the highest Rf value for acetophenone since it is a non-polar compound. The non-polar solvent system will have less affinity for the polar silica gel in the TLC plate, allowing the acetophenone to move further up the plate during the chromatography process.
Why would a substance dissolving in one solvent but not in another?
A substance may dissolve in one solvent but not in another due to differences in polarity, intermolecular forces, or chemical interactions between the solute and solvent molecules. The solute must be compatible with the solvent at a molecular level in order for dissolution to occur.

Does magnesium acetate and lithium carbonate react?
Magnesium acetate and lithium carbonate are unlikely to react because they do not contain reactive elements that would readily form a new compound. Magnesium acetate is a magnesium salt of acetic acid, while lithium carbonate is a lithium salt of carbonic acid, and they are both stable compounds under normal conditions.
Does barium acetate and lithium sulfate form a precipitate?
Yes, when barium acetate and lithium sulfate are mixed, a white precipitate of barium sulfate would form due to a double displacement reaction. This is because barium sulfate is insoluble in water.
Solute and solvent?
The solvent is the substance that is dissolving something else. The solute is what is being dissolved. For example, if you were dissolving salt in water. The water would be the solvent and the salt would be the solute.

Identify the solute and solvent in a cup of instant coffee with sugar?
Solvent= Water Solutes: Instant coffee powder, Sugar
What is the difference between solvent and solution?
The solvent in a solution is dissolving the solute. A solution is groups of molecules that are mixed in a completely even distribution. Basically a solute dissolved in a solvent. An example of a solvent would be water and a solute could be sugar. The sugar would dissolve in the water which would be a solution.
Why would a substance dissolving in one solvent but not in another?
A substance may dissolve in one solvent but not in another due to differences in polarity, intermolecular forces, or chemical interactions between the solute and solvent molecules. The solute must be compatible with the solvent at a molecular level in order for dissolution to occur.
What is a solute and a solvent?
A solute is the solid that is dissolved in a liquid. The solvent is the liquid in which something is dissolved in. For example, with salt water, the Na and Cl are the two solutes, and the H2O is the solvent. Also They Both Make A Solution. For example, to make a solution out of saltwater, you would take salt, which would be your solute, and water, which would be your solvent. To be more precise, a solvent is what does the dissolving and the solute is what is being dissolved. the answer above is not incorrect per se, just not all inclusive. an example not described by the previous answer is that of carbon dioxide dissolving in water. therefore, the solute does not have to be a solid. further the solvent doesnt have to be liquid. the solvent can be a liquid or a gas and the solute can be a solid, liquid, or gas.
How many TOTAL ions (barium cations plus acetate anions) would be produced as aqueous species in the water solvent if four molecules of barium acetate dissolved?
If four molecules of barium acetate dissolve in water, they would dissociate into a total of 8 barium cations (Ba2+) and 4x2=8 acetate anions (C2H3O2-). So, there would be a total of 8 + 8 = 16 ions produced: 8 barium cations and 8 acetate anions.
When nail polish is dissolved in acetone which substance is the solute and which is the solent?
the solvent in mainly Ethyl Acetate and the solute is ... I actually don't know. Mabe Google it.
