What is the equation when zinc metal is added to a solution of copper II chloride?
The equation is: Zn(s) + CuCl2(aq) --> ZnCl2(aq) + Cu(s)
What is observed when sodium sulphite solution is added to copper chloride solution?
When sodium sulfite solution is added to copper chloride solution, a white precipitate of copper sulfite forms. This precipitation reaction occurs because sodium sulfite reacts with copper chloride to form insoluble copper sulfite.
What is observed when a solution of potassium iodide is added to lead nitrate name the type of reaction solution?
When a solution of potassium iodide is added to lead nitrate, a yellow precipitate of lead iodide is formed. This is a double displacement reaction where the cations and anions switch partners to form the products.
What happens when you add Cu to hydrochloric acid?
When copper (Cu) is added to hydrochloric acid (HCl), a chemical reaction occurs where the copper reacts with the hydrochloric acid to form copper chloride (CuCl2) and hydrogen gas (H2). This reaction is represented by the following equation: 2HCl + Cu -> CuCl2 + H2.
What would you observe if astatine solution is added to sodium bromide solution?
When astatine solution is added to sodium bromide solution, a reaction is likely to occur where astatine displaces bromine to form astatide ions. This would result in the formation of astatide ions in solution and sodium bromide precipitating out as a solid, which can be observed as a color change or cloudy appearance in the solution.
What is the equation when zinc metal is added to a solution of copper II chloride?
The equation is: Zn(s) + CuCl2(aq) --> ZnCl2(aq) + Cu(s)
What energy change was observed when a seed is added to a supersaturated solution?
Nucleation is an endothermic process.
What chemical is being tested if a compound is added to a solution of hydrochloric acid and the solution is observed to see if a reaction takes place?
reactivity
When a solution of copper II chloride is added to a solution of potassium sulfide a double replacement reaction occurs and forms a black precipitate write an equation for the exchange of Ions?
CuCl2(aq) + K2S(aq) --> CuS(s) + 2KCl(aq) K and Cl are spectators so the net ionic would be: Cu2+(aq) + S2-(aq) --> CuS(s)
What is observed when sodium sulphate solution is added to barium chloride?
A white precipitate of barium sulphate is formed when sodium sulphate solution is added to barium chloride solution. This is due to the formation of an insoluble salt, barium sulphate, which appears as a white solid in the solution.
What is observed when sodium sulphite solution is added to copper chloride solution?
When sodium sulfite solution is added to copper chloride solution, a white precipitate of copper sulfite forms. This precipitation reaction occurs because sodium sulfite reacts with copper chloride to form insoluble copper sulfite.

What precipitate is formed if you add HCl to CuO and then add BaCl2?
HCl and CuO form CuCl2 and H2O, BaCl2 does not react with CuCl2 so it may react with water so the precipitate are of Ba(OH)2 Added: But this is not the case because to dissolve CuO first you'll need a bit more acid to get it completely dissolved. If the solution would become neutral then Cu(OH)2 would precipitate at concentration of [Cu2+] more than 1.6*10-5 (because Ks=1.6*10-19) rather than Ba(OH)2 (Ks=10-10)
What is observed when potassium iodide is added to the solution of lead nitrate?
A yellow precipitate of lead iodide forms, while potassium nitrate remains in solution. This reaction is a double displacement reaction with an exchange of ions between the two compounds.
What would be observed when NaCl is added to water?
When NaCl is added to water, the NaCl crystals dissolve and dissociate into Na+ and Cl- ions. This creates an electrolyte solution where the ions are free to move around in the water. The solution may also experience a temperature change due to the dissolution process.
