Yes, polyurethane dispersions are usually anionic and have very large molecular weights.
A solution without ions is called a nonionic solution. This means that the solute molecules in the solution do not dissociate into charged particles like ions.
Yes, ions are charged molecules by definition. There are two types cations (with positive charges) and anions (with negative charges).
Ions are not a mixture; they are atoms or molecules that have gained or lost electrons, becoming electrically charged. Mixtures are combinations of substances that can be physically separated, while ions are not separate substances but rather different forms of the same substance.
When an acid dissolves in water, the molecules of the acid break apart into ions. Specifically, the acid molecules donate protons (H+ ions) to the water molecules, resulting in the formation of hydronium ions (H3O+) and negatively charged ions from the acid. This process is called ionization or dissociation.
Magnesium bromide (MgBr₂) has a giant ionic structure. In this structure, magnesium ions (Mg²⁺) and bromide ions (Br⁻) are arranged in a three-dimensional lattice held together by strong electrostatic forces of attraction between the oppositely charged ions. This results in a high melting and boiling point, characteristic of ionic compounds. In contrast, simple structures typically involve covalent bonds and individual molecules.
No, giant covalent structures do not contain charged ions. They are formed by a network of covalent bonds between atoms, where electrons are shared between them rather than transferred to form charged ions. Examples of giant covalent structures include diamond and graphite.
Atoms that gain or lose electrons become ions, not molecules. Ions are charged particles due to an imbalance of protons and electrons. Molecules are formed when atoms are bonded together by sharing electrons.
Because they dissociate into charged ions. Because they dissociate into charged ions.
Molecules that carry positive or negative electrical charges are called ions. Positively charged ions are called cations, while negatively charged ions are called anions. Ions are formed when atoms gain or lose electrons.
Sodium ions are attracted to negatively charged particles or molecules, such as chloride ions in salt or negatively charged sites on proteins or other biological molecules. This attraction is due to the electrostatic force between positive and negative charges.
Water molecules are polar. Charged particles such as ions attract water molecules. Positive ions often have a "shell" of water molecules around them, pointing their negative O atoms at the central ion, both in solution and in the solid forms (hydrates)
H2O -> H + + OH - A positively charged proton, H +, and a negatively charged hydroxide, OH -.
Ions, charged atoms
They are molecules.No they are generally called molecules. However there are polyatomic ions that are charged molecules, such as SO42-
Ions. They are charged molecules or charged atoms.
Ionic compounds are made up of ions (positively and negatively charged atoms) held together by electrostatic forces. These ions do not form molecules with covalent bonds because they do not share electrons. Instead, the ions arrange in a crystal lattice structure.
Ionic bonding between the sodium and chloride ions in NaCl is broken when the compound is dissolved in water. The partially positively charged hydrogen atoms in water molecules are attracted to the negatively charged chloride ions, and the partially negatively charged oxygen atoms are attracted to the positively charged sodium ions, allowing the ions to separate and be surrounded by water molecules.
