In water, which is a polar molecule, ions care surounded by water molecules depending on the charge of the ion. Positive ions form eletrostatic interactions with the oxygen in water and negative ions, with the hydrogens.
Polar molecules are easily dissolved in water because they form hydrogen bonds, sort of the same principle behind the interactions that happen between ions and water molecules.
A polyatomic ion.
electrical molecule
This is the bicarbonate ion. It firms a weak alkali when dissolved.
P(3-) is an anion.
Chloride would be a negative ion in sodium chloride dissolved in water.
Lactic acid has one ion per molecule when dissolved in water.
Ammonia is a weak base. When dissolved in water, it can accept a hydrogen ion from the water molecule to form ammonium ion (NH4+) and hydroxide ion (OH-).
When NaNH2 is dissolved in an alcohol, it acts as a strong base that can deprotonate the alcohol molecule on its α-carbon, forming an alkoxide ion. This alkoxide ion can undergo further reactions like nucleophilic substitution or elimination reactions.
These layers of water molecules surrounding an ion or polar molecule are collectively called a hydration shell. The water molecules orient themselves around the ion or molecule to shield its charge or polarity, allowing it to remain dissolved in the water.
The Ion that is dissolved in a solution.
An ION is an atom that has lost or gained electrons. Thereby becoming a charged species. Once an atom becomes a charged species it is NO longer an atom but an ION . e.g. Sodium atom, symbol ' Na '. has 11 protons, 12 neutrons, and 11 electrons. When it loses (ionises) an electron it becomes a sodium ion. So sodium now has 11 protons, 12 neutrons, and 10 electrons . 11 protons (11+) and 10 electrons (10-). Doing a little sum 11+ 10- = 1(+) Hence the charge on the sodium ion is'+1' . Symbolically, shown as ' Na^(+) ' . and is named a sodium CATION. Similarly Chlorine atom, symbol ' Cl '. has 17 protons, 18 neutrons, and 17 electrons. When it has electron affinity it gains an electron it becomes a chloride ion. So chlorine now has 17 protons, 18 neutrons, and 18 electrons . 17 protons (17+) and 18 electrons (18-). Doing a little sum 17+ 18- = 1(-) Hence the charge on the chloride ion is'-1' . Symbolically, shown as ' Cl^(-) ' . and is named a chloride ANION.
The hydronium ion is a water molecule bonded to a hydrogen ion (H+). This bond forms when a water molecule donates a proton to another water molecule, creating the hydronium ion (H3O+).
No a molecule is a molecule, polar or nonpolar.
when a water molecule gains an hydrogen ion from another water molecule
An acid furnishes an H+ when dissolved in water.
An ion has an electrical charge.
A dissolved sulfate ion is colorless. In solution, sulfate ions do not impart any color to the solution.
