Quick questions on Acids, bases and pH - TCE Chemistry (Tasmania)

Q: What is the Bronsted-Lowry model?

A Bronsted-Lowry acid donates a proton (H^+); a base accepts one. When an acid donates a proton it forms its conjugate base, and when a base accepts one it forms its conjugate acid. The two species differ by a single proton.

Q: What is self-ionisation of water?

Water ionises slightly: 2H_2O H_3O^+ + OH^-.

What is the Bronsted-Lowry model?

Show answer

A Bronsted-Lowry acid donates a proton (

\text{H}^+

); a base accepts one. When an acid donates a proton it forms its conjugate base, and when a base accepts one it forms its conjugate acid. The two species differ by a single proton.

What is self-ionisation of water?

Show answer

Water ionises slightly:

2\text{H}_2\text{O} \rightleftharpoons \text{H}_3\text{O}^+ + \text{OH}^-
