What else can I help you with?
Can a base donate or accept or bond with a hydroxide ion?
Yes, a base can accept a proton from a hydroxide ion, forming a new chemical bond. When this happens, the base becomes protonated.
When does water act as a base and an acid?
molecules in water that release hydrogen ions (H+) are acids, while molecules in water that release hydroxide (OH-) are bases. In water solutions, acids affect water molecules, producing hydronium (H3O+) and bases also affect water molecules, producing hydroxide (OH-) ions.
Is hydroxide ion basic?
Yes, hydroxide ion (OH-) is a basic ion because it can accept a proton (H+) to form water (H2O), resulting in an increase in the concentration of hydroxide ions in solution.
What base is present in base?
The base present in bases is typically a hydroxide ion (OH-). This hydroxide ion is responsible for the alkaline properties of bases, as it can accept a proton from an acid to form water.
What molecule loses a proton to form the hydroxide ion?
Water (H2O) donates a proton (H+) to form the hydroxide ion (OH-).
What kind of proton acceptor is a bronsted-lowry?
A Brønsted-Lowry proton acceptor is a species that can accept a proton by forming a coordinate covalent bond with the proton. This can be a molecule or an ion that has an available lone pair of electrons to bond with the proton. Examples include ammonia (NH3) and hydroxide ion (OH-).
How is a hydroxide ion produced?
A hydroxide ion (OH-) is produced when a water molecule (H2O) donates a proton (H+) to another molecule or substance. This transfer of a proton results in the formation of a hydroxide ion and a positively charged cation.
Why does an aqueous solution of ammonia acts as a weak base?
Ammonia acts as a weak base in aqueous solution because it can accept a proton from water to form the ammonium ion (NH4+) and hydroxide ion (OH-). The reaction is reversible, and only some of the ammonia molecules will accept a proton, resulting in a partial dissociation and a low concentration of hydroxide ions produced.
Can ammonia NH3 be classified as a base even though it does not contain the hydroxide ion OH Why or Why not?
Yes, ammonia can be classified as a base because it behaves as a proton acceptor, forming ammonium ion (NH4+) by accepting a proton (H+). While it does not contain the hydroxide ion like strong bases do, it still has the ability to accept protons and undergoes the same characteristic reactions as bases.
How many protons are in hydroxide ion?
The hydroxide ion is OH-. There is one proton in a hydrogen atom and eight in an oxygen atom. Therefore, there are 9 protons in a hydroxide ion.
How can bicarbonate be a weak base if it doesn't contain hydroxide ion?
The bicarbonate ion is a base because it's a proton acceptor, that being one of the definitions of a base.
Is ammonia acid basic or neutral?
Ammonia is a basic compound because it can accept a hydrogen ion (proton) from water to form ammonium hydroxide, which increases the concentration of hydroxide ions in solution.
