what is the difference between ionic and nonionic surfactants?
14926
A non-ionic surfactant has no charge groups in its head. The head of an ionic surfactant carries a net charge. If the charge is negative, the surfactant is more specifically called anionic; if the charge is positive, it is called cationic.

Most ionic compounds are soluble in water. This is because polar water molecules have a strong attraction for charged ions. The charged ions become solvated as they dissociate into water.

Shortly: because the ions already present in ionic compounds are soluble in water due to their electric charge. ... Whereas ionic compounds are more soluble (in the terms above described) the covalent compounds are also soluble.

Alcohol ethoxylate is a nonionic (uncharged) surfactant that helps the water slide off your dishes better and thus helps them dry faster. ... Citric acid, which RB (the company that makes Jet-Dry) calls a complexing/sequestering agent, is really good at grabbing calcium ions out of hard water.

What is the difference between a polyatomic ion and an ionic compound? The most basic difference is that a polyatomic ion is a cluster of atoms with a net charge. An ionic compound is electrically neutral (no net charge). ... E.g. Sulfate (SO4 ^2-) is a polyatomic ion, unlike barium sulfate (BaSO4) which is a compound.

Re: Polar vs nonpolar vs ionic The formation of an ionic bond is the result of the transfer of one or more electrons from a metal onto a non-metal. Polar bonding is the unequal sharing of electrons between two different non-metal atoms.

Most ionic compounds are soluble in water because water is a highly polar solvent and is able to effectively solvate the metal ions. ... Indeed, sodium chloride, while highly soluble in water, is only slightly soluble in methanol, and is nearly insoluble in ethanol and longer-chained alcohols.

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.

Soap molecules are sodium or potassium salts of long-chain carboxylic acids. They form scum upon reaction with calcium and magnesium ions present in hard water. Detergent molecules are ammonium or sulphonate salts of long-chain carboxylic acids. They do not form insoluble precipitates with calcium and magnesium ions.

The Difference between the chemical composition of soaps and detergents are as follows: ... Soaps are sodium (Na) salts or Potassium (K) salts of some long chain carboxylic acids whereas detergents are ammonium or sulphurated salts or long chains of carboxylic acids (COOH).

A basic definition of an ionic compound is that they are molecules that consist of charged ions. ... 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.

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.

Detergents usually made out of surfactants. Basicly, if we assume the molecule as a chain, one end of the chain prefers to stay in the water (hydrophilic) while the other end prefers to stay out of the water (hydrophobic).

All ionic compounds are soluble in water to some extent, but the degree of solubility varies. While some compounds dissolve almost completely, others dissolve to such a small extent that they are simply called insoluble compounds. Such compounds include calcium sulfate, silver chloride, and lead hydroxide.

Most ionic compounds are soluble in water. This is because polar water molecules have a strong attraction for charged ions. ... Kerosene is a non-polar organic solvent and dissolves non-polar covalent compounds.

Soluble ionic substances and strong acids ionize completely and are strong electrolytes, while weak acids and bases ionize to only a small extent and are weak electrolytes. Nonelectrolytes are substances that do not produce ions when dissolved in 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. ... Polar substances are not likely to dissolve to a significant degree in nonpolar solvents. For example, ionic compounds are insoluble in hexane.
