IB Chem Acids SL
| Question | Answer |
|---|---|
| Arrhenius acid | Release H+ ions |
| Bronsted Lowry acid | H+ donor |
| Amphoteric | can act as either an acid or a base |
| Amphiprotic | a type of amphoteric substance that specifically can act as either an acid or base by accepting or donating hydrogen ions |
| Acid + base --> | salt + water |
| Acid + metal --> | salt + hydrogen |
| Acid + metal carbonate --> | salt + water + carbon dioxide |
| Strong acids and bases | completely dissociate (split up) into ions in aqueous solution |
| Weak acids and bases | partially dissociate into ions in aqueous solution |
| Acid + metal oxide --> | salt + water |
| Hydronium ion | H3O+ |
| Arrhenius base | Release OH- ions |
| Bronsted Lowry base | H+ acceptor |
| Conjugate acid base pair | 2 chemical species with one proton difference |
| Hydrogen ion concentration and pH conversion formula | [H+] = 10^-pH |
| Conversion between pH and pOH (one not in data booklet) | pKw = 14 = pH + pOH |
| Equivalence point | The stoichiometric point - volume where the solution has been neutralised. |
| End point | The pH where the indicator colour change is detectable to the human eye. |
