IB Chemistry SL 3.1.1 Brønsted-Lowry theory

IB Chemistry syllabusFirst assessment 2025
Focus on Brønsted-Lowry questions by spotting proton acceptance or donation, explaining pH change in water, and writing acid dissociation equations.
How this is tested
- identify ammonia as a Brønsted-Lowry base when it accepts a proton to form NH4+ in NH3 + H2O + CO2 -> NH4HCO3
- explain why the nitrogen-containing group in strychnine raises pH by accepting H+ from water and acting as a base
- write an acid dissociation equation for HCN as HCN rightleftharpoons H+ + CN- or with water forming H3O+ + CN-
