Yes they are.
Have another go at writing the question.
NiBr2 (nickel(II) bromide) is soluble in water, ethanol, and other polar solvents.
Yes, strontium bromide is soluble in ethanol. Ethanol is a polar solvent, and strontium bromide is an ionic compound, so it dissolves easily in polar solvents like ethanol.
Glucose is soluble in ethanol.
Acetone, Ethanol.
If by "wet erase" markers you mean water-soluble markers, the answer is - usually yes. The surface preparation for dry erase boards (whiteboards) is different from the way you would prepare a surface for water-soluble markers. As a consequence, it is not uncommon for water soluble markers to leave a stain on a whiteboard that requires some other solvent to remove. If a wet permanent marker is used on a dry erase board, it can sometimes be removed with an appropriate solvent, but often the whiteboard will be permanently stained (which you might expect from a permanent marker)
Yes, mannitol is soluble in ethanol. It is typically considered highly soluble in alcohols like ethanol and isopropanol.
Have another go at writing the question.
yes, it is much more soluble in ethanol than in water.
NiBr2 (nickel(II) bromide) is soluble in water, ethanol, and other polar solvents.
Yes, urea is soluble in ethanol. Urea is a polar compound that forms hydrogen bonds with the polar solvent ethanol, which allows it to dissolve in ethanol.
Yes, ethanol resistant markers are suitable for use in laboratory settings where exposure to ethanol-based solutions is common.
Yes, oxygen is slightly soluble in ethanol. However, ethanol has a low solubility for oxygen compared to other solvents.
No, sawdust is not soluble in ethanol. Sawdust is insoluble in ethanol because it is a mixture of large particles of wood fibers that do not dissolve in the liquid.
Yes, chloroform is soluble in ethanol. Chloroform is a non-polar solvent, while ethanol is a polar solvent. When mixed together, the non-polar chloroform will dissolve in the polar ethanol due to their differing solubility properties.
Permanent marker inks contain three main ingredients: colorant, carrier, and resin. A colorant, usually dyes or pigments, is what gives markers their permanence, and, of course, their color. A dye is usually a coloring material dissolved in a solvent, making it a soluble dye. On the other hand, a pigment is an insoluble coloring matter. Solvents are used as the carrier in permanent markers. Alcohol, such as ethanol or isopropanol, is an environmentally friendly solvent. It also evaporates quickly, allowing permanent markers to dry faster. The last component, resin, is a polymer that promotes adhesion. This also adds to the permanence of markers. The resin sticks like glue to most of the surfaces the marker is written on causing the pigment to attach to surfaces. These markers are generally not truly permanent as, on most surfaces, they do not stain but form a surface layer that can be removed by high pressure cleaning or solvents such as acetone, and they will eventually wear away over time. You can now gather that the so called permanent marker, can be removed because the resin component in the marker ink is soluble in acetone.
biphenyl is soluble in ethanol and also in most of organic solvents
