According to the Brønsted-Lowry definition, a base is a compound that can -keyword- accept H+, and an acid anything that can give H+.
A base is a substance that can accept hydrogen ions (H+) or donate hydroxide ions (OH-) in a chemical reaction. Bases are the opposite of acids and are considered proton acceptors.
A base accepts hydrogen ions by providing a pair of electrons to form a covalent bond with the hydrogen ion. This results in the formation of a new molecule, either a water molecule or a molecule with a negative charge.
The characteristic of a base that enables it to accept hydrogen ions is its ability to donate an electron pair to form a bond with the hydrogen ion. This is due to the presence of lone pairs of electrons on the base molecule or ion.
No, not all bases can accept hydrogen ions. Only bases with available lone pairs of electrons can accept hydrogen ions. These include compounds such as hydroxides, amines, and carbonates.
The stronger the base, the more readily it can accept hydrogen ions. Bases with stronger basicity have a higher affinity for hydrogen ions, meaning they can more easily donate an electron pair to form a bond with the hydrogen ion.
