Co2+ + 2SO4
When barium sulfate is added to water, it forms a suspension in which the particles do not dissolve in the water. This suspension is not soluble in water and can be filtered out. Barium sulfate is almost insoluble in water, which makes it useful for certain medical tests such as barium sulfate contrast studies.
Calcium + Copper sulfate ----> Calcium sulfate + Copper It is a single displacement reactions. The products are Calcium Sulfate (white, insoluble) and fillings of copper(reddish-brown).
Yes. Iron is more reactive than copper, so will displace it from a compound. If you put a piece of iron into copper sulfate solution, it will be soon coated with a deposit of orangey red copper.CuSO4 + Fe --> FeSO4 + Cu
Nothing will happen. Displacement reaction only happens when the element is more reactive than the salt solution. An example will be the otherwise. If you put aluminum metal into a solution of Copper (II) Sulfate. The aluminum metal will displace copper metal and you will have a solution of Aluminum Sulfate and copper metal. As long the element you put into the salt solution is more reactive than the cation of the solution, it will displace the metal.
The evidence that the liquid obtained from the copper(II) sulfate pentahydrate was water is that the colorless liquid did not change color or show any sign of chemical reaction when exposed to air. Additionally, the liquid evaporated over time, leaving behind white crystals, which is consistent with the properties of water that can be driven off as vapor.
Write the reaction when potassium sulfide is put into water:
This compound is soluble in water.
When cobalt II fluoride is put into water, it will dissociate into its ions: Co^2+ and F-. The reaction can be represented as CoF2 (s) → Co^2+ (aq) + 2F- (aq).
Any reaction occur when gold is put in copper sulfate.
When iron (II) sulfate is put into water, it dissolves to form Fe2+ ions and SO4 2- ions. The chemical equation is: FeSO4 (s) → Fe2+ (aq) + SO4 2- (aq).
Pouring water on it because when it is heated it turns to an endothermic reaction and the hydrated part is boiled put of the compound it is then Anhydrous copper sulphate. When you add water it is hydrated again and this is an exothermic reaction. Which can get extremely hot so don't pour it on your hand and then hydrate it.
When nickel sulfate is put into water, it dissociates into its ions - nickel (II) ions and sulfate ions. These ions then interact with water molecules through hydration to form a homogeneous solution.
When nickel is put in a copper (II) sulfate solution, a displacement reaction occurs where the nickel replaces the copper in the solution. This results in the formation of nickel sulfate and copper metal deposits on the surface of the nickel.
Since selenium is a metalloid, and nitrogen is a nonmetal, the normal convention would require us to put nitrogen at the end, not the beginning. Se4N4 is a highly explosive compound called selenium nitride. Other forms of selenium nitride also exist, with different ratios of selenium to nitrogen.
When barium sulfate is added to water, it forms a suspension in which the particles do not dissolve in the water. This suspension is not soluble in water and can be filtered out. Barium sulfate is almost insoluble in water, which makes it useful for certain medical tests such as barium sulfate contrast studies.
When you put copper sulfate in water, it will dissolve and dissociate into copper ions (Cu2+) and sulfate ions (SO4 2-). This process creates a blue-colored solution due to the presence of copper ions in the water.
Calcium + Copper sulfate ----> Calcium sulfate + Copper It is a single displacement reactions. The products are Calcium Sulfate (white, insoluble) and fillings of copper(reddish-brown).
