Which compound forms a colored aqueous solution?
Colored aqueous solutions are a characteristic of transition compounds. The only transition compound in the above choices is CrCl3. Cr is a transition element. Hence option (b) is the correct answer.
Which ion is Coloured in aqueous solution?
Transition Metal IonColorCu2+blue-greenFe2+olive greenNi2+bright greenFe3+brown to yellow7 more rowsx26bull;Feb 12, 2020
Does ni2+ exhibit Colour in aqueous solution?
Explanation: Colour is obtained as a consequence of d-d (or f-f) transition, the presence of unpaired electrons is necessary conditions. Hence, only Ti3+ will exhibit colour in aqueous solution.
Which element can form a compound that is colored solution?
Transition metals form colored solutions and compounds because these elements have unfilled d orbitals.
Which salt forms a colored aqueous solution?
Cobalt(II) nitrate and Chromium(III) chloride solutions will be colored.
What is formed in aqueous solution?
Aqueous solution is water with a pH of 7.0 where the hydrogen ions ( H +) and hydroxide ions ( OH u2212) are in Arrhenius balance (10u22127). If the substance lacks the ability to dissolve in water, the molecules form a precipitate. Reactions in aqueous solutions are usually metathesis reactions.
How do you tell if a compound is an aqueous solution?
If a compound dissolves in water then you get an aqueous solution formed. If it does not dissolve in water then you get a solid precipitate.
