A Brønsted-Lowry acid: HNO2, HF ; A Brønsted-Lowry base
: H2SO4, C3H7NH2, NH3, CCl4 ; Neither: NaBr
Further explanation
Bronsted-Lowry acid is the chemical species that donates one or more hydrogen ions in a reaction. Whereas a Bronsted-Lowry base accepts the hydrogen ions. When it donates its proton, the acid becomes its conjugate base. The more general look at the theory is as an acid as a proton donor and a base as a proton acceptor.
To determine whether a substance is an acid or a base, we can count the hydrogens on each substance before and after the reaction. If the number of hydrogens decreased that substance is the acid because it donates hydrogen ions. Whereas if the number of hydrogens increased, that substance is the base because it accepts hydrogen ions.
Bronsted-Lowry acid is a solution that donates protons, and is known as a proton donor. It donates protons in the form of a hydrogen ion (H+). This is reinforced by the definition of an acid, which is a solution that has an excess of hydrogen ions (H+). The Bronsted-Lowry base is a solution that accepts protons, and is known as a proton acceptor.
Drag each item to the appropriate bin. Are these a Brønsted-Lowry acid or a Brønsted-Lowry base
?
- A Brønsted-Lowry acid: HNO2, HF
The HF loses an H+ ion, so it is the Brønsted-Lowry acid.
- A Brønsted-Lowry base
: H2SO4, C3H7NH2, NH3, CCl4
(CH3)3N, behaves as a Bronsted-Lowry base in water BL. An example of a Brønsted-Lowry base is ammonia (NH3) as proton acceptor.
- Neither: NaBr cannot be a component in either an acidic or a basic buffer.
