What happens when calcium hydroxide react with nitric acid?
Ca (OH) 2 + 2HNO 3 → Ca (NO 3) 2 + 2H 2 O [ Check the balance ] Calcium hydroxide react with nitric acid to produce calcium nitrate and water.
What is the formula for cobalt III hydroxide?
Co(OH)3
Cobalt(III) hydroxide/Formula
What is the chemical equation for calcium hydroxide reacts with nitric acid?
Explanation: Ca(OH)2 + 2HNO3 → Ca(NO3)2 + 2H2O. Calcium hydroxide react with nitric acid to produce calcium nitrate and water.
Does cobalt react with nitric acid?
Nitric oxide reacts with the “cobalt pentammine nitrosyl” ion, [CoIII(NH3)5(NO–)]2+, to give an intermediate, [Co(NH3)5(N2O2–)]2+, which may react further with nitric oxide to give the hydroxopentamminecobalt(III) ion, nitrite, and nitrous oxide, or with excess of cobalt(II) to give decammine-µ-hyponitrodicobalt(III) …
Is Cobalt hydroxide a base or acid?
Like iron(II) hydroxide, cobalt(II) hydroxide is a basic hydroxide, and reacts with acids to form cobalt(II) salts. It also reacts with strong bases to form solutions with dark blue cobaltate(II) anions, [Co(OH)4]2− and [Co(OH)6]4−.
What is cobalt II nitrate used for?
Uses. It is commonly reduced to metallic high purity cobalt. It can be absorbed on to various catalyst supports for use in Fischer–Tropsch catalysis. It is used in the preparation of dyes and inks.
What salt is made from nitric acid and calcium hydroxide?
Salt formation
| Hydrochloric acid | Nitric acid | |
|---|---|---|
| Potassium hydroxide | Potassium chloride | Potassium nitrate |
| Sodium hydroxide | Sodium chloride | Sodium nitrate |
| Calcium hydroxide | Calcium chloride | Calcium nitrate |
How does cobalt react with air in aqueous solution?
The actual occurrence of Co (II) in aqueous solution is as the complex ion [Co (OH 2) 6] 2+. Cobalt does not react readily with air.
What is the chemical reaction of cobalt with ammonia?
Reaction of cobalt with ammonia. Cobalt (II)ions are precipitated by ammonia: [Co (H 2 O) 6] 2+ (aq) [pink, octahedral] + 2 NH 3 (aq) [Co (OH) 2 (H 2 O) 4] (s) [blue/pink] + 2 NH 4+ (aq) The precipitate dissolves in excess amonia.
What happens when cobalt oxide is heated to 900°C?
Cobalt does not react readily with air. Upon heating the oxide Co 3O 4 is formed, and if the reaction is carried out above 900°C, the result is cobalt(II) oxide, CoO. 3 Co(s) + 4 O 2(g) 2 Co 3O 4(s)
How does Co ( II ) react with HCl in aqueous solution?
The actual occurrence of Co(II) in aqueous solution is as the complex ion [Co(OH 2) 6] 2+. Co(s) + H 2SO 4(aq) Co 2+(aq) + SO 4 2−(aq) + H 2(g) Co(II) reacts with HCl(aq) under strongly acidic conditions, forming tetrahedral chloro complexes. [Co(H 2O) 6] 2+(aq) + 4 Cl −(aq) [CoCl 4] 2−(aq) [deep blue] + 6 H 2O(l)
