Then AgI forms the precipitate in the above reaction. Group 2 perchlorates are soluble in nature and therefore soluble in water. Therefore, no precipitate will form in this reaction.Īccording to the solubility rules, AgI is an insoluble salt. and NaOH are soluble salts according to the rules of solubility. This is an example of a double displacement reaction where two ionic compounds are exchanged with each other and two new compounds are formed.
Group 1A and 2A perchlorates are naturally soluble. Mercury(II) iodide is insoluble in water. Chlorides, bromides and iodides of all metals are soluble in water, except silver, lead and mercury (II). Salts containing, or generally soluble, other than the halides of, and. All sulphides, except those formed by groups 1A, 2A and the ammonium ion, are insoluble.ħ. All carbonates and phosphates, except those formed by group 1A and the ammonium ion, are insoluble.Ħ. All base metal hydroxides except, and Group 1A hydroxides are insoluble. Moreover, sulfates except, ,, and are soluble. All common fluorides, except Group 2A fluorides, are soluble. Only the chlorides, bromides and iodides of, , and are not soluble. All common ammonium ion compounds and all acetates, chlorides, nitrates, bromides, iodides and perchlorates are soluble in nature. The solubility rules for determining the solubility of compounds are as follows: 1. This insoluble salt is known as the precipitate and hence these reactions are called precipitation reactions. It is the type of reaction in which an insoluble salt is formed by combining two solutions containing soluble salts. In is the precipitate formed in Further explanation: Precipitation reaction: It is also an example of double substitution, mafnesium has an oxidation number +2 and silver has an oxidation number +1, iodine has -1 and chlorate also -1. 2nacl(aq)+ba(oh)2(aq)⟶bacl2+2naoh naoh bacl2 without precipitate agclo3(aq)+mgi2(aq)⟶agi+mg(clo3)2Ģ) The answer is: AgI.Chemical reaction: 2AgClO₃ + MgI₂ → 2AgI + Mg(ClO₃)₂.Silver chloride forms a yellow precipitate, magnesium chlorate is a salt that dissolves in water. For each reaction, identify the precipitate or lack thereof.
