How do the test on known solutions containing cations and anions make it possible to identify the cations or anions in an unknown substance?

Answer 1

You get hands-on experience of what a positive test looks like. For example, it's hard to describe the color of manganese sulfide. But once you make a little and look at it, you'll know it again.

Answer 2

once you combine a number of those recommendations mutually, a chemical reaction will take place. via very heavily conserving a checklist of what happens after mixing extremely of each mutually, you may slender down the probabilities until you already know what each answer is. as an occasion, once you combine the NaCl answer with AgNO3, a white percipitate (AgCl) will type, although, this may not ensue in case you have been to combine NaCl and DI water as an occasion. look up the solubility policies, those will probe invaluble foe determining what substance will react with what to make insoluble salts. yet another occasion, Sodium Carbonate (Na2CO3) will react with an acid (as an occasion, HCl) to type Carbon Dioxide bubbles. NaOH will react with a sucrose sugar answer (C12H22O11) to type carbon monoxide gas.
