Nafion density in acetonitrile was ∼15% less than that in water. Acid pretreatment reduced Nafion film density by ∼15%. Unheated recast films were 22−100% soluble in a sonicated ethanol/water mixture. Commercial membranes and recast films heated for as little as 10 min were insoluble under the same conditions.

Methanol is a polar solvent, but less so than water, so we would expect ionic compounds to be less soluble in methanol. Indeed, sodium chloride, while highly soluble in water, is only slightly soluble in methanol, and is nearly insoluble in ethanol and longer-chained alcohols.

Yes, ofcourse NaHCO3 IS SOLUBLE IN WATER- When we combine the sodium bicarbonate with water It is less soluble as because the density of the water is more than the density of the sodium bicarbonate…

When the compound, Ba(C2H3O2)2, is mixed with water, the Ba(C2H3O2)2 is: soluble because compounds containing the C2H3O2− ion are soluble in water. insoluble because most compounds containing the C2H3O2− ion are insoluble in water.

Ionic compounds are soluble in water but not in organic solvent since water is a polar compound which decreases the electrostatic forces if attraction, resulting in free ions in aqueous solution. Hence they dissolve.

A solution is a homogeneous mixture of ions or molecules. Why are some ionic compounds soluble in water while others are insoluble? - Ionic compounds are insoluble when attractions between its ions are greater than attractions between its ions and polarized water molecules.

Water, even pure water, has an amphiprotic nature. This means that a small amount of ions will form in pure water. ... Thus, the proton-donating molecule becomes a hydroxide ion, OH-, while the proton-accepting molecule becomes a hydronium ion, H3O+.

MgO isn't soluble in water, so no. Magnesium oxide will react with water to form magnesium hydroxide, which still isn't very soluble, but the dilute solution that is achievable will conduct electricity to some extent.

2: Solubility of Ionic Compounds: Salts. Polar compounds tend to dissolve in water, and we can extend that generality to the most polar compounds of all—ionic compounds. Table salt, or sodium chloride (NaCl), the most common ionic compound, is soluble in water (360 g/L).
