a. Insoluble, chloride salts are insoluble with Cu(I), Ag, Hg2, Pb cations.\nb. Insoluble, because of Cu presence, the only common soluble base is NaOH, KOH, NH4OH, Ba(OH)2, Ca(OH)2, Sr(OH)2.\nc. Soluble, because of Li presence\nd. Insoluble, sulphate salts are insoluble with Ba, Ca, Sr, Pb cations.\ne. Insoluble, all carbonate salts are insoluble in water, except when the cation is Na, K or NH4.\n\npeace\nvixklen

to determine whether an acid or a base is soluble in say the universal polar solvent water, u should be knowing whether the substance is strong or weak\nnow bases like NaOH, CsOH, RbOH, Mg(OH)2 are strong bases and in solution they give us the cations and anions(mostly the hydroxyl grp)\nbases like Be(OH)2, Fe(OH)2 or 3, Cu(OH)2 or any of their oxides are weak and hence in solution they do not undergo complete dissociation and most of these are insoluble\nso in case ur not in a lab, the only way is to identify their degree of weakness

That's a difficult question to answer because magnesium hydroxide is practically insoluble in water with a ksp value of like 1.8 x 10^-11 so very little magnesium hydroxide is dissolved in water.  But if you were to compare the solubility of magnesium hydroxide at 25C with 80C my guess is that it would be more soluble at a higher temperature but only by an almost insignificant amount.  \n\nIn short, Mg(OH)2 is pretty much insoluble in water so my direct answer after all the reasoning would probably be: no, Mg(OH)2 does not fit the pattern due to its extremely low solubility.

Water.\n\nIt is the letter H to O, or H2O.

Most solutes (sugar in this case) have limited solubility (ability to dissolve) in most solvents (water in this case). This solubility varies with temperature - the hotter the solution, the higher the solubility. As mentioned in an earlier answer, this means more energy must be added to dissolve more solute. On the other hand, if energy is taken out of a solution, the solute will usually  come out of the solution, depending on the concentration.\n\nThis physical law that governs this is the 2nd law of thermodyamics.

It would largely depend on the polarity of the bond.\n\nEver hear of the "like dissolves like" rule?\nWater, being a polar molecule, will dissolve other polar molecules as well as ionic compounds.  If the colvalently bonded molecule you are trying to dissolve is polar, you have a good chance at dissolving it in water (actual solubility values will varry).  However, if the molecule is non-polar, the molecule is not going to be soluble.\n\nExample,\nWater will easily dissolve "Salt" (NaCl) since it is an ioic compound.\nWater will dissolve alcohol since alcohol has an OH group, making it polar.\nWater will not dissolve gassoline for example since it is a non-polar hydrocarbon (that is why you cant mix oil and water).

It's soluble because in water it dissociates into the sodium cation and benzoate anion,  as someone else stated it's an ionic compound, so  the extent of its solubility depends on the degree of ionisation/dissociation, which is predominantly an aqueous event

Ethanol, or ethyl alcohol.\n\nSplit the water (H2O) into H and OH.\nSplit one of the bonds of the double bond two form two new single bonds.\nAttach the H to one, the OH to the other, to form H3C-CH2OH.

20 grams\ndissolving compounds and then driving of the solvent is a common way to purify a compound. You will not lose any of the compound unless it is reactive with the solvent you dissolve it in. In the case of water and salt they are not reactive so when you drive off the water you will be left with the same amount of salt that you started with.

It has a cation or anion that isn't soluble. Stuff like NaCl won't work, because Na and Cl are always soluble. KBr has the same problem. But stuff like NaOH (the OH forms insoluble metal hydroxides) works well.\n\nBasically, you have to look at the solution and the precipitating agent and see if they'll form an insoluble compound.

Oil only.  Lipids are very much insoluble in water, because water is a polar solvent while lipids are highly nonpolar.  The rule of thumb for solutions is "like dissolves like," so a nonpolar lipid will not dissolve in polar water.  Lipids are also insoluble in salt water, because the presence of other solutes in the solvent does not affect its solubility for other solutes.  But oil is a nonpolar solvent, and is in fact a lipid itself, so lipids will dissolve in it.
