Copper sulphate add to sodium hydroxide result colour?
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.
What happens when sodium hydroxide is added to copper sulphate solution?
When sodium hydroxide is added to copper sulfate solution, a blue precipitate of copper hydroxide forms. This reaction can be summarized by the equation: CuSO4 (aq) + 2 NaOH (aq) → Cu(OH)2 (s) + Na2SO4 (aq).
Explain what happens when sodium hydroxide solution is added to ammonium hydroxide?
When sodium hydroxide solution is added to ammonium hydroxide, a double displacement reaction occurs. Ammonium hydroxide is a weak base and sodium hydroxide is a strong base. The reaction produces water, sodium hydroxide, and ammonia gas.
What will be the observation when you will add aqueous sodium hydroxide is added to aqueous iron 3 sulphate?
A brown precipitate of iron(III) hydroxide will form, along with the sodium sulfate remaining in solution. The iron(III) hydroxide precipitate will settle at the bottom of the container.
What happens when excess hydroxide solution is added to copper II sulphate solution?
When excess hydroxide solution is added to copper II sulphate solution, a precipitate of copper II hydroxide forms. The balanced chemical equation for this reaction is CuSO4 + 2NaOH -> Cu(OH)2 + Na2SO4. In this reaction, the blue color of the copper II sulfate solution turns into a light blue precipitate of copper II hydroxide.
Copper sulphate add to sodium hydroxide result colour?
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.
What happens when sodium hydroxide is added to copper sulphate solution?
When sodium hydroxide is added to copper sulfate solution, a blue precipitate of copper hydroxide forms. This reaction can be summarized by the equation: CuSO4 (aq) + 2 NaOH (aq) → Cu(OH)2 (s) + Na2SO4 (aq).
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.
Name the solution formed when sodium is added to water?
sodium hydroxide solution
Explain what happens when sodium hydroxide solution is added to ammonium hydroxide?
When sodium hydroxide solution is added to ammonium hydroxide, a double displacement reaction occurs. Ammonium hydroxide is a weak base and sodium hydroxide is a strong base. The reaction produces water, sodium hydroxide, and ammonia gas.
What is added to sodium hydroxide that will get sodium sulphate and water?
You would need to add Sulphuric acid to make Sodium Sulphate + Water :)
What will be the observation when you will add aqueous sodium hydroxide is added to aqueous iron 3 sulphate?
A brown precipitate of iron(III) hydroxide will form, along with the sodium sulfate remaining in solution. The iron(III) hydroxide precipitate will settle at the bottom of the container.
Does sodium hydroxide release protons when added to water?
No. Sodium hydroxide releases hydroxide ions, which actually take protons out of the solution. This qualifies sodium hydroxide as a base.
What do you observe when red litmus is added to a solution of sodium sulphate?
Sodium sulfate solution is neutral; the red litmus is purple.
What is the colour change when sodium hydroxide is added to iron II sulphate?
dark green (but orange - brown if left standing)
What happens when excess hydroxide solution is added to copper II sulphate solution?
When excess hydroxide solution is added to copper II sulphate solution, a precipitate of copper II hydroxide forms. The balanced chemical equation for this reaction is CuSO4 + 2NaOH -> Cu(OH)2 + Na2SO4. In this reaction, the blue color of the copper II sulfate solution turns into a light blue precipitate of copper II hydroxide.
Why does strontium sulfate becomes less soluble in an aqueous solution when sodium sulfate is added?
Sodium sulphate increases the concentration of sulphate ions. So strontium sulphate solubility decreases.
