a protic solvent is a solvent that has a hydrogen atom bound to an oxygen as in a hydroxyl group or a nitrogen
dimethylsulfoxide(DMSO) is a polar aprotic compound
Due to formation of intermolecular hydrogen bonding.
Solvent. Solvents (usually liquids) dissolve solutes, resulting in a solution. Water is a protic solvent - any solvent that has a hydrogen atom bound to an oxygen or nitrogen group. Basically, it's any solvent that contains the labile H+.
-Polar protic solvent has a hydrogen atom attached to a strongly electronegative element (e.g. oxygen) that forms hydrogen bonds. On the other hand, polar aprotic solvents are those solvents whose molecules do not have a hydrogen atom that's attached to an atom of an electronegative element.-Polar protic solvent solvate cations and anions effectively while aprotic solvents do not solvate anions to any appreciable extend.-Polar protic solvents are more suitable for SN1 reactions, while aprotic solvents are used for SN2 reactionsReference: Organic Chemistry 9/e, T.W.

The type of solvent that is best suited to dissolve an ionic or a highly polar solvent would also be highly polar, probably a polar protic solvent like water or alcohol.
salts dissolve in protic solvents do to the polar nature of salts and the solvent (like dissolves like). ie. water (protic) and sodium chloride (ionic) = Na+ + Cl- in water an example of a nonprotic solvent is DCM (dichloromethane). it is nonpolar and doesnt really react much with ions. this is something you will need to know to pass an organic chemistry.
Abstract The emission spectra of styrene (ST)-triethylamine (TEA) systems were measured under steady-state illumination conditions in some tetrahydrofuran (THF)-protic solvent mixtures. The fluorescence spectrum of the ST-TEA system in THF consists of two bands (band A at 304 nm (fluorescence of ST) and band B at 460 nm (emission from an exciplex)). The intensity of band A increased and that of band B decreased with increasing amounts of protic solvents in THF-protic solvent mixtures. The increase in the intensity of band A was explained by the decrease in the concentration of free amine owing to the hydrogen-bonding interaction (or protonation) between TEA and protic solvents. The decrease in the intensity of band B was considered to be caused by the decrease in the concentration of free amine upon the addition of protic solvents and the enhanced conversion of the exciplex to an ion pair with increasing solvent polarity. The polar effect was expressed as a function of the relative permittivity of the solution.
alcohols can be considered as polar protic solvents due to there ability to hydrogen bond
Ammonia hydroxide is a protic solvent however ethanol is aprotc or organic solvent in ethanol very week hydrogen bondings are formed so ammonia hydroxide partially soluble in ethanol when we heated it (increasing of reactivity) we can see the comlete solubility
acetic acid is a polar protic solvent. protic solvents have highly developed structures held together with H-bonds.smaller ion like F- can fit easily into these cages and becomes less nucleophile. while larger anion like, Br-can't fit and remains as anion. so becomes more available nucleophiles for attck in reaction.
It is a tri-protic acid
Protic (located in the Inner Rim).
give me the example of tri

The acetic acid provides a polar, protic solvent for the reaction to occur in. This helps to stabilize the carbocation(cholesterol). This speeds up an assists the reaction. For more information you can read the Wikipedia page on SN1 reactions, or do other research on SN1.
An SN1 reaction will occur if:The substrate can form a relatively stable carbocation (typically from a tertiary carbon)The nucleophile is relatively weakA polar protic solvent is used.An SN2 reaction will occur if:The substrate is with a relatively unhindered leaving group (typically from a methyl, primary, or secondary alkyl halide)The nucleophile is strong (usually negatively charged) and is of high concentrationThe solvent used is polar and aprotic.
Potassium is stored in not aqueous or non-protic solvents such as kerosene or hexane
Universal Solvent is the solvent found in cola and OJ.Universal Solvent is the solvent found in cola and OJ.
it waz ur face just joking i waz solvent solvent can never changes solvent is solvent
Because methanol has a protic hydrogen (O-H) which can dissociate. Typical of alcohols.
A protic acid such as hydrochloric acid, sulfuric acid or nitric acid etc.
they are very reactive towards water or strongly protic solvents.
