If you think to a precipiate this is possible when the compound is insoluble in the solvent.
Solution. In this solution, the ions of the ionic compound are surrounded by water molecules, which help to separate and stabilize the ions in the solution. This dispersion of ions allows the solution to be clear and transparent, as the individual ions do not clump together to form a precipitate.
A NaCl solution is a mixture. It has Na+ ions, Cl- ions and water.
Two sodium ions that do not form an ionic compound are Na+ ions located in separate aqueous solutions. These ions remain separate in solution and do not form a compound because they are not able to attract and bond with each other due to being surrounded by water molecules.
A base is a compound that produces hydroxide ions (OH-) in solution.
A strong electrolyte is an electrolyte that exists in solution almost entirely as ions. An example is NaCl. When NaCl dissolves in water, it dissolves almost completely to give Na+ and Cl- ions.
A compound that dissolves in water to form hydroxide ions is sodium hydroxide (NaOH). When NaOH is dissolved in water, it dissociates into sodium ions (Na+) and hydroxide ions (OH-), increasing the concentration of hydroxide ions in the solution.
An ionic compound will precipitate out of solution when the concentration of ions exceeds the solubility product constant (Ksp) for that compound. This causes the compound to exceed its solubility limit and form a solid precipitate.
Compounds that produce hydroxide ions in solution are called bases. Some common examples include sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium hydroxide (Ca(OH)2). When dissolved in water, these compounds release hydroxide ions (OH-) which can react with acids to form water and a salt in a neutralization reaction.
Chloride ions would form elements with ions of metallic elements. For example, with sodium ions, chloride ions form sodium chloride.
The compound is a base.
An acid is a chemical compound that donates hydrogen ions to a solution. This process increases the concentration of hydrogen ions in the solution, lowering its pH.
Not all the time. Only acids that react with metals will give of Hydrogen (H) Acid + Metal --> Salt + Hydrogen
