BASES....BASES...Are Compounds That Produce Hydroxide ions (OH-)....
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.
Arrhenius bases produce OH- ions by definition when dissolved in water. A Bronsted - Lowry base can produce OH- ions, but only has to produce a proton accepting group by definition. A Lewis base is defined as an electron donating group, which hydroxide ion is. So, basic compounds do produce OH- ions when dissolved in water, but not in all cases.
A salt
No, actually they produce hydrosonium ions in an aqueous medium.
Is called an alkali. Sodium hydroxide is a typical example.
Sodium hydroxide (NaOH) and potassium hydroxide (KOH) both have more hydroxide ions (OH-) than hydrogen ions (H+). These compounds are strong bases that dissociate completely in water to produce high concentrations of hydroxide ions.
Compounds that form hydroxide ions in solution include metal hydroxides like sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium hydroxide (Ca(OH)2). These compounds dissociate in water to release hydroxide ions (OH-) and cations.
Any Arrhenius base will produce the OH- ion. Ammonia is a common example. Example- NH3(g) + H2O(l) -> NH4+(aq) + OH−(aq) Other examples include: natural dissociation of water: H2O -> OH- + H3O+ sodium hydroxide: NaOH(s)->Na+(aq)+OH-(aq)
Compounds that increase the number of hydroxide ions when dissolved in water are called bases. Common examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH). When these bases dissolve in water, they dissociate to release hydroxide ions, which can increase the pH of the solution.
A base in solution will produce hydroxide or OH- ions.
Bases produce hydroxide ions (OH-) when they dissociate in water. The hydroxide ions are formed as a result of the base accepting a proton (H ion) from the water molecule, creating hydroxide ions and leaving behind a hydroxide ion. This process increases the concentration of hydroxide ions in the solution, making it basic.
The hydroxide ion (OH-) is always present in alkalis. Alkalis are chemical compounds that produce hydroxide ions in solution and have a pH greater than 7.
