Which acid is known as king of chemicals?

Aqua regis (Latin: water of king) is the triviale name of the 3:1-mixture of concentrated hydrochloric acid (HCl) and nitric acid (HNO3), capable of dissolving (by oxidation) of gold, the King of metals.The first step reaction (oxidation) will only go further when followed by the 2nd step of complex forming to the tetrachloroauraat ion AuCl4-, because too much Au3+will stop the oxidation.Au(s) + 3 NO3-(aq) + 6 H+(aq) → Au3+(aq) + 3 NO2(g) + 3 H2O(l)Au3+(aq) + 4 Cl-(aq) → AuCl4-(aq)

How do you test for the presence of iodine?

Testing for Iodide, I-Sodium iodide, NaI, is the source of iodide anion for this experiment.Reaction with bleach involves three steps. The brown color shows the presence of I3- ions.Hypochlorite ion yields chlorine:OCl- (aq) + Cl- (aq) + H2OCl2 (aq) + 2 OH-Chlorine reacts with iodide anion:Cl2 (aq) + 2 I- (aq)I2 (aq) + 2 Cl- (aq)Triiodide ion is formed:I2 (aq) + I- (aq) I3- (aq)Starch reacts with iodine and iodide to form a characteristic blue/black complex. A corn starch packing peanut is shown here.Silver ion reacts with iodide to form silver iodide, AgI.Ag+ (aq) + I- (aq) AgI (s)Reaction of iodide with sulfuric acid produces hydrogen sulfide gas and brown triiodide solution in a series of reactions:I- (aq) + H2SO4 (aq) HI (aq) + HSO4- (aq)8 HI + H2SO4 (aq) H2S (g) + 4 I2 (aq) + 4 H2OI2 (aq) + I- (aq) I3- (aq)Again, starch is used to confirm the presence of iodine and iodide.
