I have basically 12 salts to identify in exams. They are ***

Ammonium Carbonate, Ammonium Sulphate, Ammonium chloride, Aluminium Nitrate , Aluminium Sulphate, Barium chloride, Calcium Carbonate, Magnesium Carbonate, Magnesium Sulphate, Lead Nitrate, Zinc Sulphide, Zinc Sulphate

***. I will be given one of them. I know all the tests I have to undertake to identify these salts (such as ash test, flame test, sodium carbonate extract tests etc). But I would like to know if there is any quick way to easily identify my salt on looking it or some easy tests so that I get a leverage over time and could finish my tests easier. I would like to know ASAP, as I have my exams tomorrow.

Thanks in advance

  • $\begingroup$ You just need to know the test for anion and cation $\endgroup$

  • $\begingroup$ I know the tests, but it is practically time consuming.... If only i had an alternative way.. $\endgroup$

    $\begingroup$ @MukilanSC None of these tests are particularly time consuming. How fast are you meant to be doing this?? $\endgroup$

  • $\begingroup$ I have been given 3 hours for a volumetric analysis as well as this qualitative analysis and also this time includes summarizing the result of each individual test. $\endgroup$

$\begingroup$

Draw a matrix of cations vs anions, mark the possible combinations, and calculate the probabilities.

The chances are 4/12 for a sulphate, 3/12 for a carbonate, etc.

I wouldn't start testing for sulphides ;-)
