Salt Analysis Class 12 Practical PDF Free Download
Identification Of The Cation And Anion Of An Inorganic Salt Is A Component Of Salt Analysis, Sometimes Referred To As Systematic Qualitative Analysis Or Qualitative Inorganic Analysis. This Is Accomplished By Systematically Performing A Number Of Tests And Using The Observations To Confirm The Presence Or Absence Of Certain Cations And Anions.
The Cbse Class 12 Chemistry Practical Examinations Include A Section On Salt Analysis, Which Many Students Find Difficult To Understand. Because Of This, We At Byju’s Have Focused Our Efforts On Explaining This Subject In A Way That Is Simple To Comprehend And Remember. This Article Also Discusses A Few Shortcuts And Tricks That Students Might Use To Quickly Analyse The Salts They Were Given To Analyse During Their Chemistry Practical Exams.
Students Will Be Given An Inorganic Salt In The Exam, And They Must Determine Its Chemical Composition. This May Be Achieved By Specifically Identifying The Salt’s Cation And Anion.
A Flame Test Should Be Done First If The Salt Is Colourless (Since The Presence Of 3 Different Cations Can Be Confirmed By It). Picking Up A Piece Of Salt Using Test Tube Holders, Applying A Few Drops Of Concentrated Hcl To It, And Then Exposing It To The Flame Of A Bunsen Burner Are Easier Ways To Do The Flame Test.
Continue With Group-wise Preliminary Tests For Cations If The Flame Test (Or Visual Inspection) Does Not Provide Any Information About The Cation. Please Take Note That Certain Cations And The Anions Listed Below Do Not Combine To Form Salts.
You Don’t Need To Do Tests For The Corresponding Anions If You Find One Of These Cations In The Salt Analysis.
Finally, Salt Analysis Examinations Frequently Include Specific Salts. For Instance, Nh4br And Cacl2 Are The Most Popular Salts That Include The Calcium Cation (Ca2+) And The Bromide Ion (Br-), Respectively. Additionally, By Observing Their Texture And Appearance, Some Salts Can Be Recognized (For Example, Calcium Carbonate Has The Texture Of Powdered Chalk). As A Result, Going To Your Chemistry Lab And Physically Inspecting The Salts May Enable You To Analyse The Salt In The Practical Exam More Quickly.
To Identify The Anion Of The Salt, Preliminary Anion Tests Are Carried Out Group-wise In Salt Analysis. To Confirm The Presence Of An Anion In Salt After Receiving A Positive Preliminary Test Result, A Confirmatory Test Must Be Performed.
Test Tube Experiment: Add A Few Drops Of Diluted Sulfuric Acid (H2so4) To A Little Amount Of Salt (If Nothing Happens, Move On To Preliminary Test For Group 2 Anions).
There Are No Preliminary Tests For The Sulphate And Phosphate Ions (Group 3 Anions). You May Go Directly To Confirmatory Tests For The Sulphate And Phosphate Anions If No Positive Preliminary Test Results Are Obtained For Group 1 And Group 2 Anions.
When Analysing Salt. To Determine If Certain Cations Are Present In The Inorganic Salt, Preliminary Cation Tests Must Be Performed. This Is Carried Out In A Manner Like The First Tests For Anion. You Should Be Aware That Certain Cation Groups, Such Group 0 And Group 6, Don’t Have Any Preliminary Tests. Confirmatory Tests May Be Carried Out Directly On These Cations.

Identification Of The Cation And Anion Of An Inorganic Salt Is The Focus Of Salt Analysis, Commonly Referred To As Systematic Qualitative Analysis Or Qualitative Inorganic Analysis.
This Is Accomplished By Carrying Out A Systematic Set Of Tests And Utilising The Results To Confirm The Presence Or Absence Of Certain Cations And Anions. Many Students Struggle With Salt Analysis, A Subject That Is Included In Both The Cbse And Isc Class 12 Chemistry Practical Exams.
Process For Salt Analysis In Steps
- Get The Inorganic Salt Whose Cation And Anion You Need To Identify In Step 1.
- Perform Initial Testing For Each Anion Group Separately Until You Get A Positive Result. The Groups That Anions And Cations Belong To Have The Same Group Reagent And, As A Result, Have Comparable Preliminary Tests.
- After A Preliminary Test For An Anion Yields A Positive Result, Carry Out A Confirmatory Test For That Anion. (Go To Step 4 If The Outcome Is Favourable.) If Not, Return To Doing Preliminary Anions Testing.)
- Perform First Cation Testing Group-by-group Up Until You Get A Positive Result.
- Execute A Confirmatory Test For That Cation When A Positive Result Has Been Achieved.
- Now That The Cation And Anion Have Been Identified, Get The Salt’s Chemical Formula By Balancing Their Charges. For Instance, The Salt’s Chemical Formula Will Be Fecl3 If Your Cation Is Fe3+ And Your Anion Is Cl-.
Note: Another Option Is To First Identify The Cation Before Moving On To The Identification Of The Anion.
