Phosphates (PO4 3-) and carbonates (CO3 2-) are usually insoluble. Exceptions include salts of the Na+, K+, and NH4 + ions, which are soluble by rule 1.

Explanation: "Insoluble" generally means that a substance does not dissolve in water. Some examples include: sand, fats, wood, metals, and plastic. When we put them in water and try to mix them, they will not dissolve.

2: Solubility of Ionic Compounds: Salts. Polar compounds tend to dissolve in water, and we can extend that generality to the most polar compounds of all—ionic compounds. Table salt, or sodium chloride (NaCl), the most common ionic compound, is soluble in water (360 g/L).

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.

Answer and Explanation: Naphthalene is insoluble in water because it is non-polar. This means that it cannot participate in dipole-dipole interactions or hydrogen bonding...

Insoluble Compounds Not all compounds dissolve well in water. Some ionic compounds, such as calcium carbonate (CaCO3) and silver chloride (AgCl), are nearly insoluble. This is because the attractions between the ions in the crystal lattice are stronger than the attraction that the water molecules have for the ions.

Although it is insoluble in water, it is soluble to varying degrees in dilute hydrochloric-acid solutions, such as those in the stomach.

Calcium hydroxide is relatively insoluble in water, with a solubility product Ksp of 5.5 × 10−6. It is large enough that its solutions are basic according to the following reaction: Ca(OH)2 → Ca2+ + 2 OH.

Lipids are all insoluble in polar solvents like water but highly soluble in the non-polar or weakly polar organic solvents, including ether, chloroform, benzene, and acetone. In fact, these four solvents are often referred to as "lipid-solvents" or "fat-solvents".

All sodium, potassium, and ammonium salts are soluble in water. 3. The chlorides, bromides, and iodides of all metals except lead, silver, and mercury(I) are soluble in water. HgI2 is insoluble in water.

Is K2CO3 (Potassium carbonate) 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.

In chemistry, water is considered to be the universal solvent, and materials that are hydrophilic can dissolve in it. Hydrophobic molecules, however, do not dissolve in water.

No, Fatty acids are water INSOLUBLE. This is because of the HYDROPHOBIC CARBON TAIL that they possess which repels water. Infact, Fatty acids forms Micelle when mixed with water.

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. For example, nonpolar molecular substances are likely to dissolve in hexane, a common nonpolar solvent. ... For example, ionic compounds are insoluble in hexane.

Is FeCO3 (Iron (II) carbonate) soluble or insoluble in water? The answer is that it is insoluble in water. Although it is an ionic compound, it does not dissociate into its ions in water. Iron (II) carbonate is therefore insoluble in water.

Triglycerides are completely insoluble in water. ... Phospholipids are partially soluble in water, meaning that part of the molecule is attracted to water, and part of it is not. Phospholipids form important structures in water when the polar end faces water and the nonpolar end faces away from water.
