Lithium carbonate, lithium fluoride and lithium phosphate are insoluble in water. Most of the s block metals' compounds are soluble in water. All nitrates are soluble in water, so Zn (NO 3) 2 is soluble. Calculate the Ksp for Bi(OH)3 if 1.1 x 10-8 moles of Bi(OH)3 dissolve in 1.0 liter of water to form a saturated solution. Oxygen is water soluble … it's the white stuff that's left after you boil away most water (at least here in the midwest). Lithium forms some insoluble compounds. CH3OH 3. A compound which is insoluble in cold water but soluble in excess of ammonia solution is : 12th. Here are some things that are MOSTLY insoluble in water: sodium sulfate. Unlike molecular compounds, salts dissociate in solution into anionic and cationic components. When no more solute can dissolve in a solution, we say it is a saturated solution. A salt is soluble if it dissolves in water to give a solution with a concentration of at least 0.1 moles per liter at room temperature. Question.

Carbonates (CO3 2- ), oxalates (C 2O4 2- ), phosphates (PO 4 3- ), and sulfides (S2- ) except those with alkali metal ions or the ammonium ion. While some compounds completely dissolve in water and some are almost completely insoluble, many "insoluble" compounds are actually slightly soluble. PbBr 2. Salt is an ionic compound that is formed by a cation and anion. The following is for solubility in pure water, not with any common ions. Silver iodide is an insoluble salt. To determine if an ionic compound is soluble—i.e., will dissolve—in water, we use the Solubility Rules: Solubility Rules for Ionic Compounds in Water The compound is SOLUBLE if it has: 1. Solution. Answer. Low solubility means a precipitate will form. MgS, CaS, BaS are sparingly soluble. All bromides are soluble in water, except those combined with Pb 2+, so PbBr 2 is insoluble. If solid sodium iodide and solid silver nitrate are mixed together a reaction to for sodium nitrate and silver iodide occurs but it is extremely slow.
