Most of them don't, but some do give color in aquous solution, eg. copper(II) ions are blue, iron(III) = ferric ions are pale green, cobalt rose colored, KMnO4 solution is very dark purple (potassium permanganate)
Dissolved in water.
Under normal conditions CuCl2 can exist in either a solid state or in aqueous solution.
Ammonium nitrate can be dissolved in water to form an aqueous solution, but it does not exist in a liquid state naturally.
When a compound is in the aqueous state, it means that it is dissolved in water. In this state, the compound's molecules or ions are dispersed throughout the water, making it a solution. The aqueous state is often indicated by the symbol (aq) in chemical equations. This state is significant in various chemical reactions, particularly in those involving acids, bases, and salts.
No, sodium oxide cannot exist in aqueous state because it is an ionic compound that does not readily dissolve in water. When sodium oxide reacts with water, it forms sodium hydroxide, a water-soluble compound.
Sodium nitrate is a solid and is soluble in water
MgSO4 is soluble in water, which is in aqueous state (aq) or can be written as MgSP4(aq).
Corrected answer:NO,MOST of the potassium salts and ALL of the nitrates are SOLUBLE, not insoluble!!!So potassium nitrate is NOT INsolubleSome potassium salts and complexes are insoluble like Potassium Hexanitritocobaltate(III) = K3[Co(NO2)6] , etc.
Yes, silver chlorate (AgClO3) is soluble in water. When AgClO3 is mixed with water, it dissociates into its ions Ag+ and ClO3-. This allows it to dissolve and form a clear solution.
Generally salts are solid substances.
Take this as a rule: All group one salts are soluble All nitrates are soluble in water You can answer that with only one rule but better yet the two rules state that LiNO3 ( lithium nitrate) lithium being in group one and nitrates being soluble make LiNO3 soluble in water.
Calcium hydrogen carbonate, or calcium bicarbonate (Ca(HCO₃)₂), is soluble in water due to its ionic nature. When dissolved, it dissociates into calcium ions (Ca²⁺) and bicarbonate ions (HCO₃⁻), which are stabilized by interactions with water molecules. This solubility allows it to exist in an aqueous state, making it important in natural processes such as water hardness and the formation of stalactites and stalagmites in caves.
