Protic solvent

In chemistry a protic solvent is a solvent that has a hydrogen atom bound to an oxygen (as in a hydroxyl group) or a nitrogen (as in an amine group). More generally, any molecular solvent which contains dissociable H+, is called a protic solvent. The molecules of such solvents can donate an H+ (proton). Conversely, aprotic solvents cannot donate hydrogen.

Polar protic solvents are solvents that share ion dissolving power with aprotic solvents but have an acidic hydrogen. These solvents generally have high dielectric constants and high polarity.

Common characteristics of protic solvents :

Examples are water, methanol, ethanol, formic acid, hydrogen fluoride and ammonia.

Polar aprotic solvents are solvents that share ion dissolving power with protic solvents but lack an acidic hydrogen. These solvents generally have intermediate dielectric constants and polarity.

Common characteristics of aprotic solvents:

Examples are dimethyl sulfoxide, dimethylformamide, dioxane and hexamethylphosphorotriamide, tetrahydrofuran.

Polar protic solvents are favorable forSN1 reactions, while polar aprotic solvents are favorable for SN2 reactions.

Apart from solvent effects, polar aprotic solvents may be essential for reactions which use strong bases, such as reactions involving Grignard reagents or n-butyllithium. If a protic solvent were to be used, the reagent would be consumed by a side reaction with the solvent.

An example of a dipolar aprotic solvent is methylpyrrolidone.

Properties of common solvents

The solvents are grouped into non-polar, polar aprotic, and polar protic solvents and ordered by increasing polarity. The polarity is given as the dielectric constant. The properties of solvents that exceed those of water are bolded.

Question:What is an example of a solution in which the solute and solvent are not easily distinguishable?

Answers:Solute: Water Solvent: Ethyl Alcohol I think you are looking for two substances which are both liquid at room temperature. The water may be ice when you add it, but when it melts it will look the same as the clear alcohol. On the other hand, the water could easily be separated from the alcohol merely by freezing it. So maybe what you want are two substances that are nearly identical, such as xylene and benzene, or ethanol and methanol. Or normal water and deuterium oxide.

Question:

Answers:In a solution, the part in greater quantity is the solvent. Air is a solution of oxygen in nitrogen An alloy is a solution, such as stainless steel salt water is a solution as is sugar water soda pop has CO2 dissolved

Question:i cant for the life of me find an answer someone hlep me out! i need help with this and please justify why u say something.... science guys please help me!

Answers:The only thing I can think of is air

Question:I am doing a paper on solutions and i need examples: Solute Solvent gas liquid gas solid liquid liquid liquid solid solid liquid solid solid

Answers:gas in liquid: all soft drinks, CO2 in Pepsi for example gas in Solid: gases absorbed on Carbon Tablets liquid in liquid: vinegar in water liquid in solid: Mercury in Gold Solid in liquid: Salt in water solid in solid: All metal alloys, like Brass

Solute and Solvent - Dissolving :A sugar cube is dissolved and the process is explained.

Solute Bye Solvent :this is my groups project that we did for physical science. we tryed to make it educational but gangster as possible, so sit back and enjoy the works of me daryl darion and tyler . hope you learnsomething
