Worked Solution & Example Answer:The qualitative test for chloride ions in solution is add dilute nitric acid then add silver nitrate solution i) Describe what you see if this test is carried out on a solution containing chloride ions - Edexcel - GCSE Chemistry - Question 2 - 2016 - Paper 1
Step 1
Describe what you see if this test is carried out on a solution containing chloride ions.
Answer
When the qualitative test for chloride ions is performed by first adding dilute nitric acid followed by silver nitrate solution, a white precipitate forms. This white precipitate is silver chloride (AgCl), indicating the presence of chloride ions in the solution.
Step 2
Step 3
Describe the difference between a qualitative and a quantitative test.
Answer
Qualitative tests are designed to identify the presence or absence of a substance but do not provide information about the amount or concentration of that substance. For example, the test for chloride ions shows whether chloride is present but not how much.
In contrast, quantitative tests measure the actual amount or concentration of a substance in a sample. These tests provide numerical results that can indicate the level of a specific ion or compound, allowing for more precise assessments of various conditions.
