I posted this question ealier today, but i cant seem to find it and add to it....
here is my problem, it is for a Science Olympiad competition this coming saturday, and i just got information for this competition today.
we will have ten solids: sodium bicarbonate, sodium sulfite, magnesium hydroxide, calcium carbonate, sodium dihydrogen phosphate, ammonium chloride, zinc chloride, potassium iodide, potassium hydroxide, and aluminum nitrate.
we will be able to choose one of the four chemical solutions to use in identifying the substances: 3M HCl, 3M NaOH, Phenolphthalein indicator solution, or 0.1M AgNO3.
my question i guess is what solution would be the best in determining what the substances are? and should we look at any other characteristics besides what happens with the solution in determining what it is??
i have looked all over the internet, and i am finding really nothing. i havent had a chance to look at any books, but my teacher/coach does have many different chemistry books....
what do you suggest?
Thanks for all of your help.
