IB Chemistry 3.1.6 Strong vs. weak acids/bases Questions
Learn how exam questions distinguish strong and weak acids or bases through ionization, pH, conductivity and reaction rate in named examples.
How this is tested
- explain why CH3COOH or HNO2 has higher pH than equal-concentration HCl: only partial ionization occurs
- predict slower H2 or CO2 production with Mg or carbonates in CH3COOH than in equal-concentration HCl
- distinguish 0.10 mol dm^-3 HCN from 0.10 mol dm^-3 HCl by higher pH, lower conductivity, or slower reaction
