It can be a substiuet in chemistry.But never in coocking.
This depends on each compound; for chlorides the solubility is comparable.
Potassium salts of fatty acids should yield soft soaps because they are more soluble in water than sodium salts of fatty acids (which yield hard soaps). They contain more water, so they are softer.
For sodium and potassium bromide is more soluble than chloride.
Why should it be INsoluble? Contrarily, it is soluble as ALL common potassium salts are! And even more so, most perchlorates are soluble as well!
sodium bromide can conduct electricity though not in high quantitiesAdded:So does potassium bromide, as all ionic salts do (more or less) 'in solutae'
Sodium bicarbonate is NaHCO3, potassium carbonate is KHCO3. The difference is that sodium and potassium are two different elements, though they have very similar properties. Potassium bicarbonate is more soluble in water.
Like most (but not all !) salts they are more soluble in hot than in cold water.
Sodium chloride is more soluble in water than KCl.
Ascorbic acid is an acid. Sodium or potassium ascorbate are salts and either neutral or slightly alkaline.The salts are rather more readily absorbed by the body than the acid but those on a low sodium diet should be aware that sodium ascorbate adds to their sodium intake.
Sodium nitrate is more soluble than sodium chloride; sand is insoluble in water.
K; Potassium
Sodium carbonate is more soluble.
Potassium chloride is more soluble in water. However, in general, both compounds are highly soluble in water.
