They are not soluble, therefore they do not precipitate or form a color....a.k.a....no reaction...
When zinc sulfate reacts with potassium hydroxide, zinc hydroxide is formed as a white precipitate, while potassium sulfate remains in solution. This reaction is a double displacement reaction where the cations and anions of the two compounds switch partners.
When you mix copper sulfate and potassium hydroxide, a blue precipitate called copper hydroxide is formed. This is due to the reaction between copper ions from copper sulfate and hydroxide ions from potassium hydroxide. The chemical equation for this reaction is CuSO4 + 2KOH → Cu(OH)2 + K2SO4.
dark green (but orange - brown if left standing)
The precipitate formed from the reaction between silver nitrate and potassium chloride is white in color. This precipitate is silver chloride, which is insoluble in water and forms when the silver ions from silver nitrate react with chloride ions from potassium chloride.
the precipitate is calcium sulfate (CaSO4) and its white in color
Yes, a precipitate is formed when ammonium nitrate and potassium hydroxide are mixed. The reaction between these two compounds forms ammonium hydroxide and potassium nitrate, which results in the formation of a white precipitate of ammonium nitrate.
The precipitate formed when a calcium salt reacts with sodium hydroxide solution is white. This white precipitate is calcium hydroxide, which is sparingly soluble in water.
When sodium hydroxide is added to copper oxide, a blue precipitate of copper hydroxide is formed. The color of the precipitate is due to the formation of copper ions in solution.
When potassium hydroxide and sodium chloride are mixed together, no precipitate is formed as both compounds are soluble in water. Both potassium hydroxide and sodium chloride dissociate into their respective ions in water, forming a clear solution.
The precipitate formed when barium chloride reacts with sodium hydroxide is barium hydroxide (Ba(OH)2).
Beryllium hydroxide
When copper sulfate is added to sodium hydroxide, a blue precipitate of copper hydroxide is formed. The color change observed is from the initial blue color of copper sulfate to the blue precipitate of copper hydroxide.
The salt formed by potassium hydroxide and sulphuric acid is potassium sulphate (K2SO4). Though if potassium hydroxide is the limiting reagent potassium bisulphate (KHSO4) will also form.
When zinc sulfate reacts with potassium hydroxide, zinc hydroxide is formed as a white precipitate, while potassium sulfate remains in solution. This reaction is a double displacement reaction where the cations and anions of the two compounds switch partners.
Strontium bromide and potassium sulfate will produce a precipitate of strontium sulfate.
When you mix copper sulfate and potassium hydroxide, a blue precipitate called copper hydroxide is formed. This is due to the reaction between copper ions from copper sulfate and hydroxide ions from potassium hydroxide. The chemical equation for this reaction is CuSO4 + 2KOH → Cu(OH)2 + K2SO4.
The precipitate formed from the reaction between silver nitrate and potassium carbonate is silver carbonate (Ag2CO3), which is a white solid.
