6.11 Qualitative Analysis
 
Qualitative Analysis of a Salt 
A technique used to identify the cation and anion present in a salt by analysing its physical and chemical properties.
 
The image is an infographic titled ‘STEPS IN THE QUALITATIVE ANALYSIS OF A SALT.’ It outlines four steps in the analysis process: 1. Observation on the physical properties of the salt. 2. Effect of heat on the salt. 3. Test for anions and cations. 4. Confirmatory tests for cations and anions. Each step is represented by a numbered circle with a brief description next to it. The infographic is branded with the ‘Pandai’ logo.
 
Conformation Test for Anions
 
Confirmatory Test for Cations
  • Salt must be dissolved in water first before the confirmatory test.
  • The colour of the aqueous solution is observed.
Reactions between Cations and Sodium Hydroxide Solution, NaOH

Reactions between Cations and Sodium Hydroxide Solution, NaOH
