Solubility Rules

Solubility Rules 1. All common compounds of Group I and ammonium ions atomic number 18 dissolvable. 2. All treats, acetates, and chlorates be disintegrable. 3. All binary compounds of the halogens (other than F) with metals argon soluble, except those of Ag, Hg(I), and Pb. Pb halides atomic number 18 soluble in juicy water.) 4. All sulfates be soluble, except those of barium, strontium, calcium, lead, silver, and hydrargyrum (I). The latter trey are jolly soluble. 5. Except for line up 1, carbonates, hydroxides, oxides, silicates, and phosphates are insoluble. 6. Sulfides are insoluble except for calcium, barium, strontium, magnesium, sodium, potassium, and ammonium. Solubility Rules for bonce Compounds in Water fat-soluble Salts 1. The Na+, K+, and NH4+ ions form soluble salts. Thus, NaCl, KNO3, (NH4)2SO4, Na2S, and (NH4)2CO3 are soluble. 2. The nitrate (NO3-) ion forms soluble salts. Thus, Cu(NO3)2 and Fe(NO3)3 are soluble. 3. The chloride (Cl-), bromide (Br-), and iodide (I-) ions chiefly form solubl 1 year ago 4. The sulfate (SO42-) ion principally forms soluble salts. Exceptions let in BaSO4, SrSO4, and PbSO4, which are insoluble, and Ag2SO4, CaSO4, and Hg2SO4, which are slightly soluble.

Insoluble Salts 1. Sulfides (S2-) are commonly insoluble. Exceptions hold Na2S, K2S, (NH4)2S, MgS, CaS, SrS, and BaS. 2. Oxides (O2-) are ordinarily insoluble. Exceptions include Na2O, K2O, SrO, and BaO, which are soluble, and CaO, which is slightly soluble. 3. Hydroxides (OH-) are usually insoluble. Exceptions include NaOH, KOH, Sr(OH)2, and Ba(OH)2, which are solubl e, and Ca(OH)2, which is slightly soluble. ! 4. Chromates (CrO42-) are usually insoluble. Exceptions include Na2CrO4, K2CrO4, (NH4)2CrO4, and MgCrO4. 5. Phosphates (PO43-) and carbonates (CO32-) are usually insoluble. Exceptions include salts of the Na+, K+, and NH4+ ions.If you want to reward a full essay, order it on our website: OrderCustomPaper.com
