Adding drops of sodium hydroxide solution can help identify cations present in a solution. Some cations will not form a precipitate so they will be identified by the flame test while others can form a white or a colored precipitate.

Detection of cations of the first analitic group
 
02:48
Cations of the first analitic group of cations are silver ion Ag + , lead ion Pb 2+ , and mercury (I) ion, Hg 2 2+ . Their presence in an aqueous solution is proved by different reagents. They all form a percipitate with HCl, hydrochloric acid. To prove the presence of a silver ion, Ag + , in a solution we add some HCl to the solution, which forms a percipitate of AgCl, silver chloride. Then we dissolve AgCl in ammonia, NH3, forming a new aqueous solution of the silver ion complex [Ag(NH3)2]+ . When we add some more HCl to the solution, a white AgCl percitipate is formed, which is proof for silver ions in our sample. Lead ion, Pb 2+ , is determined by dissolving the percipitate of PbCl2, formed when HCl is added to the sample, in boiling water and then adding chromate ions to it in the form of K2Cr2O7 . The newly formed yellow percipitate is PbCrO4 , lead chromate, which is proof for Pb 2+ ions in our sample. Mercury (I) ion, Hg 2 2+ , forms Hg 2 Cl 2 percipitate when HCl is added to the sample. When ammonia is added to Hg2Cl2 , a gray percipitate of Hg (black) and HgNH2Cl (white) is formed, which is proof for mercury (I) ions in our sample.

Tricks for Qualitative Analysis | Cations | Jee Mains, Advance, NEET, BITSAT and AIIMS

Hello Guys, Memorizing Qualitative analysis isn't a good idea at all. So, IITian explains is going to make it easiest ever. Learn some super crazy tricks for Salt analysis. Qualitative Cation Analysis The composition of relatively complex mixtures of metal ions can be determined using qualitative analysis, a procedure for discovering the identity of metal ions present in the mixture (rather than quantitative information about their amounts). The procedure used to separate and identify more than 20 common metal cations from a single solution consists of selectively precipitating only a few kinds of metal ions at a time under given sets of conditions. Consecutive precipitation steps become progressively less selective until almost all of the metal ions are precipitated. Group 1: Insoluble Chlorides Most metal chloride salts are soluble in water; only Ag+, Pb2+, and Hg22+ form chlorides that precipitate from water. Thus the first step in a qualitative analysis is to add about 6 M HCl, thereby causing AgCl, PbCl2, and/or Hg2Cl2 to precipitate. If no precipitate forms, then these cations are not present in significant amounts. The precipitate can be collected by filtration or centrifugation. Group 2: Acid-Insoluble Sulfides Next, the acidic solution is saturated with H2S gas. Only those metal ions that form very insoluble sulfides, such as As3+, Bi3+, Cd2+, Cu2+, Hg2+, Sb3+, and Sn2+, precipitate as their sulfide salts under these acidic conditions. All others, such as Fe2+ and Zn2+, remain in solution. Once again, the precipitates are collected by filtration or centrifugation. Group 3: Base-Insoluble Sulfides (and Hydroxides) Ammonia or NaOH is now added to the solution until it is basic, and then (NH4)2S is added. This treatment removes any remaining cations that form insoluble hydroxides or sulfides. The divalent metal ions Co2+, Fe2+, Mn2+, Ni2+, and Zn2+ precipitate as their sulfides, and the trivalent metal ions Al3+ and Cr3+ precipitate as their hydroxides: Al(OH)3 and Cr(OH)3. If the mixture contains Fe3+, sulfide reduces the cation to Fe2+, which precipitates as FeS. Group 4: Insoluble Carbonates or Phosphates The next metal ions to be removed from solution are those that form insoluble carbonates and phosphates. When Na2CO3 is added to the basic solution that remains after the precipitated metal ions are removed, insoluble carbonates precipitate and are collected. Alternatively, adding (NH4)2HPO4 causes the same metal ions to precipitate as insoluble phosphates. Group 5: Alkali Metals At this point, we have removed all the metal ions that form water-insoluble chlorides, sulfides, carbonates, or phosphates. The only common ions that might remain are any alkali metals (Li+, Na+, K+, Rb+, and Cs+) and ammonium (NH4+). We now take a second sample from the original solution and add a small amount of NaOH to neutralize the ammonium ion and produce NH3. (We cannot use the same sample we used for the first four groups because we added ammonium to that sample in earlier steps.) Any ammonia produced can be detected by either its odor or a litmus paper test. A flame test on another original sample is used to detect sodium, which produces a characteristic bright yellow color. The other alkali metal ions also give characteristic colors in flame tests, which allows them to be identified if only one is present. Metal ions that precipitate together are separated by various additional techniques, such as forming complex ions, changing the pH of the solution, or increasing the temperature to redissolve some of the solids. For example, the precipitated metal chlorides of group 1 cations, containing Ag+, Pb2+, and Hg22+, are all quite insoluble in water. Because PbCl2 is much more soluble in hot water than are the other two chloride salts, however, adding water to the precipitate and heating the resulting slurry will dissolve any PbCl2 present. Isolating the solution and adding a small amount of Na2CrO4 solution to it will produce a bright yellow precipitate of PbCrO4 if Pb2+ were in the original sample. Summary In qualitative analysis, the identity, not the amount, of metal ions present in a mixture is determined. The technique consists of selectively precipitating only a few kinds of metal ions at a time under given sets of conditions. Consecutive precipitation steps become progressively less selective until almost all the metal ions are precipitated. Other additional steps are needed to separate metal ions that precipitate together.

Cation Test: Lead(II) Ions
 
03:11
Solutions containing lead(II) ions are typically colourless in colour. To test for the presence of lead(II) ions in solution, you may use either the sodium hydroxide test or the ammonia test. 1) Sodium Hydroxide Test - To a sample of your solution, add a few drops of sodium hydroxide solution. A white precipitate forms. Upon addition of excess sodium hydroxide, the white precipitate dissolves. 2) Ammonia Test - To a sample of your solution, add a few drops of ammonia solution. A white precipitate forms. Upon addition of excess ammonia solution, the white precipitate remains insoluble.

Lead is found in many salts like lead nitrate and lead acetate as lead (II) ion. In group I, lead (II) ions are precipitated as their chlorides by adding dilute hydrochloric acid to their solutions. Lead chloride solution in hot water when reacts with potassium iodide solution to form yellow precipitate of lead iodide and potassium chromate to form yellow precipitate of lead chromate. This video explains how to test the presence of group I lead ion in a given salt.
