are dyes soluble in water?
441722
Dyes are usually soluble—or can be made to be soluble—in water. Once a dye is dissolved in water, the material to be dyed can be immersed in the dye solution. ... Pigments are generally not soluble in water, oil, or other common solvents.

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.

Dyes and pigments are substances that impart color to a material. ... Dyes are much finer than pigments. Therefore dyes are not UV stable whereas pigments are usually UV stable. Dyes, also known as colorants in which the coloring matter is dissolved in liquid, are absorbed into the material to which they are applied.

We call substances that dissolve in water soluble. Sugar and salt are examples of soluble substances. Substances that do not dissolve in water are called insoluble. Sand and flour are examples of insoluble substances.

Solubility of iodine and iodine compounds Most iodine compounds are readily soluble in water or alcohol. Inorganic iodines are highly water soluble.

Vinegar is soluble in water as both are polar in nature, moreover acetic acid being an electrolyte ionised in water therefore it is soluble in water.

Is Na3PO4 (Sodium phosphate) soluble or insoluble in water? The answer is that it is soluble in water. It is an ionic compound which readily dissociates into its ions in water.

Ionic compounds are soluble in polar solvents and insoluble in non-polar solvents. Polar solvents like water decrease the electrostatic forces of attraction, resulting in free ions in aqueous solution. Hence, ionic compounds dissolve in polar solvents.

Methanol is freely soluble (miscible) in water because the molecule has a small R-group (methyl) and thus is very similar to water in structure. Hydrogen bonding dominates the intermolecular forces in methanol so water is a very good solvent to dissolve methanol.

When you mix sugar with water, the sugar dissolves to make a transparent solution. Salt is soluble in water too. Substances that do not dissolve in water are called insoluble substances.

In general, PCBs are relatively insoluble in water, and the solubility decreases with increased chlorination (see Table 4-3). PCBs are also freely soluble in nonpolar organic solvents and biological lipids (EPA 1980b).

Ionic compounds are soluble in water but not in organic solvent since water is a polar compound which decreases the electrostatic forces if attraction, resulting in free ions in aqueous solution. Hence they dissolve.

Why are some ionic compounds soluble in water while others are insoluble? ... attractive forces between water molecules and its ions. Ionic compounds are insoluble when attractions between its ions are greater than attractions between its ions and polarized water molecules.

A mixture in which a substance has fully dissolved in water is called a solution and the substance is said to be soluble. An example of this type of mixture is sugar in water. Here the sugar dissolves fully to give a clear solution. In this example, sugar is the solute and water is the solvent.

Although it is an ionic compound, it does not dissociate into its ions in water to any appreciable degree. - NH4+ (Ammonium ion) are soluble.

Argon has approximately the same solubility as oxygen and it is 2.5 times as soluble in water as nitrogen . This chemically inert element is colorless and odorless in both its liquid and gaseous forms. It is not found in any compounds.

For example, ionic compounds, which are very polar, are often soluble in the polar solvent water. Nonpolar substances are likely to dissolve in nonpolar solvents. ... Polar substances are not likely to dissolve to a significant degree in nonpolar solvents. For example, ionic compounds are insoluble in hexane.
