What happens when CuSO4 reacts with NH4OH?
What happens when CuSO4 reacts with NH4OH?
Complete step by step solution: When ammonium hydroxide NH4OH is added to the dropwise in the sulphate solution the copper ion Cu2+ reacts with the 2 molecules of ammonia. The copper reacts to form copper hydroxide. Copper hydroxide is a hydroxide of copper and a pale blue-greenish precipitate is formed.
What happens when ammonia reacts with copper sulphate?
The reversible copper sulfate reaction When concentrated ammonia solution is added, copious quantities of white smoke are produced, heat is generated and the yellow-green complex turns into a very dark blue copper ammonia complex. The reaction can then be reversed by adding more acid.
What is the product of NaOH CuSO4?

| 1 | NaOH + CuSO4 → Na2SO4 + Cu(OH)2 |
| 2 | NaOH + CuSO4 + HCHO → H2O + Na2SO4 + Cu2O + HCOOH |
| 3 | NaOH + CuSO4 + C6H12O6 → H2O + Na2SO4 + Cu2O + HCOOH |
| 4 | NaOH + CuSO4 + HCHO → H2O + Na2SO4 + Cu2O + HCOONa |
Is LiF an acid or base?
LiF is obviously neutral, because it’s a salt of very strong acid and very strong base.
Is SnCl2 acid or base?
In SnCl2,the tin is electrin deficient centre. Due to presence of two chlorine atoms the electron deficiencyagain increases. Hence erectron rich centre readily attacks to the electron deficient tin centre. Here sn centre acts as lewis acid….
Is NH4CN basic or acidic?
NH4CN is a salt of weak acid HCN (Ka = 6.2 × 10-10) and a w.
Is KCN acidic basic or neutral?
KCN is a basic salt. Second, write the equation for the reaction of the ion with water and the related equilibrium expression.
Is NaCH3COO acidic basic or neutral?
A salt formed between a weak acid and a strong base is a basic salt, for example NaCH3COO. These salts are acidic or basic due to their acidic or basic ions as shown in the Table 1….
What is the pH of CH3COOK?
NH4Cl solution is acidic, its pH < 7. NaNO3 solution is neutral, its pH = 7. CH3COOK and Na2CO3 solutions are basic their pH > 7.
Which has highest pH value?
Sodium carbonate (Na2CO3) is a salt of strong base and weak acid. Its sodium is also basic and its pH value will be more than 10….
Why is potassium acetate acidic?
Potassium Acetate is a salt that is formed by an equal number of acetate ions and potassium ions. Potassium ion comes from a strong base named potassium hydroxide and acetate ion comes from the weak acid named as acetic acid. Potassium acetate is actually a conjugate base of acetic acid which is a weak acid.
When should I take potassium acetate?
Potassium Acetate Injection is used as a source of potassium, for addition to large volume intravenous fluids, to prevent or correct hypokalemia (low potassium) in patients with restricted or no oral intake of potassium.
