Qualitative Analysis (2)

Steps in the qualitative analysis of a salt (2)

Effect of heat on the salt

Steps in the qualitative analysis of a salt (3)

Test for anions and cations

Steps in the qualitative analysis of a salt (4)

Confirmatory tests for cations and anions

Observations of the Physical Properties of Salts (1)

Observing the physical properties of salts such as colour & solubility in water is the first step to make inferences on the possibility of the presence of cations & anions in the salt

Observations of the Physical Properties of Salts (2)

Even though the solubility test of the salts does not confirm the identities of the ions present, it helps us narrow down the possible identities of the ions present

Observations of the Physical Properties of Salts (3)

The colour of the salt is one of the physical properties that enables us to make inference on the cation present in the salt

Observations of the Physical Properties of Salts (4)

All white soluble salts dissolve in water to form colourless salt solutions

Observations of the Physical Properties of Salts (5)

Salts form coloured solutions due to the presence of ions in transition elements
