When chromium(II) sulfate, CrSO4, is dissolved in water, it dissociates into its respective ions: Cr2+ and SO4 2-. The balanced chemical equation for this dissociation is: CrSO4 (s) → Cr2+ (aq) + SO4 2- (aq). This reaction is a dissolution reaction, where the solid compound breaks apart into its constituent ions in the presence of water.
When chromium bromide is put into water, it dissociates into ions. The reaction is: CrBr2(s) → Cr2+(aq) + 2Br-(aq).
Write the reaction when potassium sulfide is put into water:
When sulfuric acid and potassium dichromate react in ethanol, they form chromium(III) sulfate, potassium sulfate, water, and carbon dioxide. This is a redox reaction where the dichromate ion is reduced to chromium(III) while sulfuric acid is acting as a catalyst. The products will vary depending on the specific conditions of the reaction.
in hydrated form it is soluble but in anhydrous form it is insoluble
When chromium(II) iodide is put into water, it undergoes a redox reaction where chromium(II) ions are oxidized to chromium(III) and iodide ions are reduced to iodine. This results in the formation of chromium(III) hydroxide and iodine.
This compound is soluble in water.

When potassium dichromate reacts with sulfuric acid, the following reaction takes place: K2Cr2O7 + 2H2SO4 -> Cr2(SO4)3 + K2SO4 + 2H2O + 3O2. This reaction results in the formation of chromium(III) sulfate, potassium sulfate, water, and oxygen gas as products.
The chemical reaction between water and calcium sulfate (CaSO4) results in the formation of calcium sulfate dihydrate (CaSO4·2H2O), commonly known as gypsum. This reaction is exothermic and reversible, meaning that when gypsum is dissolved in water, it can eventually revert back to calcium sulfate and water.
yes you do. this is because the anyhdrate was white (crystals) and after adding water, it turned blue
Sodium sulfate dissolves in water to produce a solution of sodium sulfate.
The balanced equation for the reaction of chromium with water is: 2 Cr + 6 H2O -> 2 Cr(OH)3 + 3 H2.
The reaction between dissolved sodium hydroxide and aqueous hydrogen sulfate forms aqueous sodium sulfate and water vapor. This is a neutralization reaction where sodium hydroxide and hydrogen sulfate ions combine to form sodium sulfate and water. The balanced chemical equation for this reaction is 2NaOH + H2SO4 -> Na2SO4 + 2H2O.
