M6 IQ3 - Quantitative Analysis

How are solutions of acids and bases analysed?

titration

titration curves — strong acid/strong base

titration curves — strong acid/weak base

titration curves — weak acid/strong base

conductivity graphs — strong acid/strong base

conductivity graphs — strong acid/weak base

conductivity graphs — weak acid/strong base

model neutralisation of strong and weak acids and bases

calculate and apply the dissociation constant (Ka) and pKa (pKa = -log10 (Ka)) to determine the difference between strong and weak acids

acid/base analysis techniques that are applied in industries

acid/base analysis techniques that are applied by Aboriginal and Torres Strait Islander Peoples

acid/base analysis techniques that are applied using digital probes and instruments

soft drink — conduct a chemical analysis of a common household substance for its acidity or basicity

wine — conduct a chemical analysis of a common household substance for its acidity or basicity

juice — conduct a chemical analysis of a common household substance for its acidity or basicity

medicine — conduct a chemical analysis of a common household substance for its acidity or basicity

buffer

conduct a practical investigation to prepare a buffer and demonstrate its properties

describe the importance of buffers in natural systems
