Chemistry Qualitative Salt Analysis Cheatsheet

The Short Story:
Here’s a cheatsheet for qualitative salt analysis with all the common ions and tests included. I left out the ones which are generally not done at school, but in case you feel that I should include something, change any content, etc your suggestions are welcome.

The Long Story:
It’s a known fact that I don’t attend far too many classes at school; and I’m constantly in need of notes and such stuff from others. Having done this for quite a few years, I’ve got into a habit of creating ‘cheatsheets’ for referring to before exams, because I hardly remember anything any day. Take for example the chemistry practicals, almost all of which I didn’t attend last year (and only one of organic this year).

Thus, for today’s chemistry practical (which went sorta fine except I’m not sure of my cation), I made a reference sheet for qualitative salt analysis. I wouldn’t have done it, but the Web doesn’t seem to have any good stuff on this. The upshot was that I was working till 1.42 am typing out stuff that I dozed off at the computer table itself. I’d though it was a nice idea to do it, it’d help me remember the things too, but *argh*, those bloody subscript and superscript almost killed me.

This stuff is really useful for CBSE class 11 and 12 students, for the qualitative salt analysis practicals; and I guess for other folks interested in chemistry too. Feedback and suggestions for improvement are welcome.

Update 1: I made a cellphone version of the salt analysis cheatsheet too.
Update 2: The cheatsheet has been updated. It’s now been condensed to a four-page affair, and some useless footnotes have been removed. A few tips have been added towards the end. In case you’re (still) interested in the old one, download version 1 of salt analysis cheatsheet.

Update 3: Kartik Mankad has informed me of some possible discrepancies in the cheatsheet. I’ll repeat them from everyone’s benefit here – but I haven’t checked this out in a lab. There might be a few things I skipped because our teachers told us not to bother with them. Kartik’s given some nice tips though. Thanks!

  1. Sulphite, nitrite, and sulphide are not in CBSE course.
  2. As mentioned right under the heading of ‘cations’ it says, “When phosphate is detected cations of group 3 and later are absent”. This rule is violated for many salts, for example nickel phosphate.
  3. The procedure for ring test is mentioned wrong. Our teacher specifically said NOT to add HNO3 and use only H2So4.
  4. Under flame test you may also add Pb salts, which give a bluish white flame.
  5. Deliquescence (the ability to absorb moisture) is a great tool in determining the salt/group. Example, Mg salts are HIGHLY deliquescent. MgCl2 makes the filter paper (on which it is kept) wet in minutes.

    Awesome. Thanks. No suggestions though, since this probably the first time in 6 months I am seeing the analysis and tests again ;)

    Nice artemis style fonts, by the way :P

    With nitrate however, there may be a case with different cation combinations that the test may show no colour at all. But that doesn’t mean it’s not nitrate, so one has to move on with the regular test just to confirm it.

    I say this because we have a salt of this type in our lab. I believe it is Ammonium Nitrate …

      Ammonium Nitrate is highly explosive…it is NEVER…i said NEVER kept in school labs!!!

    you had to use “MAsOn” didnt you!!!

    btw thanks this will come in handy
    as me and rach had made the organic compound cheatsheet
    only didnt get time to make this one.

    @Ramit: The paper pellet test to see if fumes intensify is very good for detecting nitrates as far as I know…and I don’t think out lab has ammonium nitrate.

    @Boris: I was also thinking of making a organic chemistry cheatsheet, when I get some free time.

    Very very nice work.

    I have my Chemistry practicals on 7th Feb. Could you make a small 1 page PDF with this, which I can print and put to suitable use :P ?

    @NT: There’s *quite* a bit of text actually in that, isn’t there? I did make a one sheet version, to be printed on both sides, but frankly, it wasn’t very usable because of the small font size. Here’s what I can advise you – use the cellphone version of the cheatsheet. It’s quite handy, and loads easily. And in case you don’t want to take the ‘added risk’ of carrying a cellphone, download that file anyway, and open it using any respectable archiver. Extract the file ‘book.txt’, and then print it with the smallest font size that you can humanely bear (and I’m sure it still won’t be readable). Methinks you can go ahead and print this version, AND keep it practicals. Many people in our school have done so. Who’ll bother to check pockets?

    Also worth noting is that if none of the indicatory tests for anions come up it can either be Nitrate or Acetate.

    If its Acetate, then most labs only have Lead Acetate.

    this is sooo fucking useful to me man
    hey….i have a suggestion….

    thisll help if we haven attended any practical class and have no friggin clue abt it ryte?
    cuz i really suck in chem and the teachers in
    my school(indianhighschool dubai)arent hot stuff
    so they dont really explain stuff properly

    Dear Ankur,

    U R A COOOOOOOOOOOOOOOl GUY.

    I always support the freshers….young generation, opposing elders in my category.

    I see my daughter in u since she is same like u; ofcourse I was the one who asked her to be with me from KG most of the time instead of behaving like the usual parent in everything. She will appear for Boards this year. I will ask her to visit your site & be in touch.
    She is forced to be in school today since computer practical exam – semester.

    Where r u now for higher studies? We r in Kuwait but the chemistry teacher is lousy not teaching anything..just reads the text book; all the children r going for tuitions to learn something.

    God is surely blessing u for having these healthy, nice ideas which are so helpful for your generation.

    May God shower His blessings upon u,guide u easily in your further studies & career.

    BEST AND HAPPY WISHES
    Jacqueline

    The things u have posted i already know it what i want to know is that some salts dissolve in both dil. and conc. h2so4 den hw to distinguish bt. dat??and some salts do not dissolve in water at all what to do for that??and it has mostly happened with me that a salt shows reaction for 2 cations and 2 anions any suggestion regarding all these……..!!!

    Thank you for sharing. You’ve left out the As3+ radical.
    It is a group II radical (lead group) and gives yellow precipitate on passing H2S. Dissolved in conc. HNO3. Gives yellow ppt. with Ammonium molybdate and white with magnesia mixture.

    Thanx dude.
    because of this cheatsheet, i was able to rock my preboards. never have i ever gotten more than 18 out of 30 in practicals, but because of u, i scored full in the practical and writing part. i guess i should study for viva also to increase the 28 to 30 ;)

    i would say that i love u, but that sound gayish, so i’ll go with- i am a fan of urs and will remember u till the day i lose my memory
