are molecular solids soluble in water?

Solubility in water Most molecular substances are insoluble (or only very sparingly soluble) in water. Those which do dissolve often react with the water, or else are capable of forming hydrogen bonds with the water.

Many ionic solids, such as silver chloride (AgCl) do not dissolve in water. The forces holding the solid AgCl lattice together are too strong to be overcome by the forces favoring the formation of the hydrated ions, Ag+(aq) and Cl-(aq).

Most ionic compounds are soluble in water. Polar water molecules have a strong attraction for charged ions and the charged ions become solvated as they dissociate into water and ionic compounds are soluble in water.

Sugar and ethanol are covalent compounds that are soluble in water, because they contain O-H groups that can H-bond to the water. Nonpolar compounds like hydrocarbons have weak intermolecular attractive forces. ... Its molecules have little attraction to each other or to the water molecules.

Amino acids are generally soluble in water and insoluble in non-polar organic solvents such as hydrocarbons. This again reflects the presence of the zwitterions. In water, the ionic attractions between the ions in the solid amino acid are replaced by strong attractions between polar water molecules and the zwitterions.

yes KBr is Soluble in water. Water molecules are polar. ... These water molecules are moving, so they will collide with the solute ions or molecules. As they collide, they will form a bond with the ions or molecules of the substance; and carry the ion or molecule away from the rest of solute.

Molecular solids are solids whose composite units are molecules. Molecular solids are held together by intermolecular forces; dispersion forces, dipole–dipole forces, and hydrogen bonding. Ice (solid H2O) and dry ice (solid CO2) are molecular solids.

Compounds which exist as solid ionic crystals dissolve in water as ions, and most of them are highly soluble in water. "Highly soluble" is a somewhat elastic description, but generally means soluble to at least the extent of forming 0.1 to 1.0 molar aqueous solutions.

Metallic bonds are not soluble in water because: ... They are held together by strong metallic bonds and so no solvent to solute attractions could be stronger than these, so these substances are insoluble also they don't have the necessary intermolecular forces (namely hydrogen bonds) that are present in water.

Many things are soluble in water - common salt, sugar, honey, jaggery, alcohol, acetone, glycerine, baking soda and so on. There is a limit for solubility of each substance in water at a given temperature.

Many polar molecular substances are soluble in both water and hexane. For example, ethanol is miscible with both water and hexane. The following generalization is helpful: Substances composed of small polar molecules, such as acetone and ethanol, are usually soluble in water.

Nonpolar substances are not likely to dissolve to a significant degree in polar solvents. For example, nonpolar molecular substances, like hydrocarbons, are likely to be insoluble in water. ... Substances composed of small polar molecules, such as acetone and ethanol, are usually soluble in water.

Ionic compounds are also more soluble in water than covalent compounds. This is because water dissolves polar substances, which is the consistency of the ionic compound, whereas covalent compounds are non-polar.

Covalent bonds do not dissolve in water, but some covalent compounds do. ... Water molecules are attracted to each other by strong H-bonds. A polar solute may be attracted to the water molecules as strongly as the water molecules are attracted to each other.

The small aldehydes and ketones are freely soluble in water but solubility falls with chain length. ... The reason for the solubility is that although aldehydes and ketones can't hydrogen bond with themselves, they can hydrogen bond with water molecules.

yes KBr is Soluble in water. Water molecules are polar. The O end has a partial negative charge, and the 2 H's end has a partial positive charge. ... These water molecules are moving, so they will collide with the solute ions or molecules.

Ionic compounds, such as sodium chloride, are also highly soluble in water. Because water molecules are polar, they interact with the sodium and chloride ions. In general, polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar solutes. This concept is often expressed as “Like dissolves like.”
