What is the solute and solvent of a liquid erasers?
The solute in a liquid eraser is typically various polymers and chemicals that help erase pencil marks. The solvent is usually a mixture of organic compounds like alcohols or hydrocarbons that help keep the eraser in a liquid form for easy application.
What are the three properties that a compound must possess in order for it to function well as an extraction solvent?
- the solvent must be miscible with the organic solute and not miscible with water- also any chemical reaction is permitted- higher yield of extraction- easy and complete recovery of the solvent
How can the solubility of a solution be decreased?
Solubility of a solution can be decreased by adding a solute that is insoluble or less soluble in the solvent, reducing temperature, or increasing pressure for gases. These can shift the equilibrium towards the formation of solid precipitates, reducing the amount of solute that can remain dissolved in the solution.
Is the concentration change after you add water to solution?
Adding more solute to a solution will increase its concentration. Adding more solvent will only dilute it. Think of salt water. The salt is the solute, and water is the solvent. Add salt and it becomes a more concentrated solution. Add more water, and it is more dilute. Simple and easy once you think it through.
What does solvent mean in biology?
1_A solvent is either a liquid or gas that takes into itself a solute (which can be in the state of a solid, liquid or gas) and creates a solution.If we use a simple and easy example, we can get a handle on the idea. Take a glass of warm water, put a teaspoon of table salt in it, and stir it. The salt will dissolve in the water and "disappear" from view. The water is the solvent here, the salt is the solute in this example, and the resulting salt water is a solution that we created. It's that simple.Wikipedia has more information, and a link is provided to their post on solvent.A solvent is also the substance that dissolves the solute.2_The solvent is the substance that the solute or solutes dissolve (disappear in solvent) in and it forms the bulk of the solution . In a suger solution, sugar is the solute and water is the solvent .
How does temperature affect the amount of solute that can dissolve in a amount of solvent?
For the solute to be soluble the solvent must first break the existing bonds between the solute. Increasing heat energy breaks more of the existing bonds of the solute which allows the solvent to make more new bonds with the solute particles. This leads greater solubility of the solute in the solvent. (I don't think this applies if gas is the solute and solvent)
What is the solute and solvent of lipstick?
In lipstick, the solute typically consists of pigments, oils, and waxes that create the color and texture. The solvent is often a mixture of oils or fatty substances that help dissolve the pigments and provide a smooth application. Together, these components create a stable formulation that allows the lipstick to maintain its shape and color while being easy to apply.
What is the solute solvent and the purpose for hair spray?
In hair spray, the solute is typically a polymer or resin that provides hold and structure, while the solvent is usually a volatile organic compound like alcohol or water that helps dissolve the solute and allows for easy application. The primary purpose of hair spray is to provide styling support by keeping hair in place and maintaining the desired style throughout the day. Additionally, it can add shine and reduce frizz.
How does a mixture separated?
it separates the soil by boiling the water and then you are left with the soil but if you want the water to be kept you use filtration!!! easy see The solvent is evaporated, the solute remain as solid crystals.
In liquid liquid extraction what factors you consider to choose select the proper solvent as an example consider the extraction of benzoic acid from water?
In choosing a proper solvent for liquid-liquid extraction of benzoic acid from water, factors to consider include solubility of the solute in the solvent, density difference between the solvent and water for easy phase separation, and the ability of the solvent to form a distinct phase with water. In this case, a non-polar solvent like diethyl ether or ethyl acetate could be suitable as they have good solubility for benzoic acid and can form a separate layer with water for easy separation.
Describe how you can tell the difference between an unsaturated solution and a saturated solution?
An unsaturated solution can dissolve more solute at a given temperature, whereas a saturated solution contains the maximum amount of solute that can be dissolved in the solvent at that temperature. You can tell the difference by observing whether there is still undissolved solute present in the solution (unsaturated) or if the solution is clear with no solute visible (saturated).
How can you differentiate between steel and diamond?
It is very easy to differentiate between diamond and steel. They have a completely different appearance, and a completely different chemical composition, and very different physical properties. I don't think that anyone gets these things confused.
