What is the ion responsible for the color change when adding copper sulfate to ammonium hydroxide?
The deep blue colour of the resulting solution is due to the cuprammonium ion, more formally the hexaamminecopper(II) ion. Its formula is [Cu(NH3)6]2+ where the numbers inside the brackets should be subscripts, and the 2+ should be a superscript.
What is the colour of chloride ion?
Chloride ion is colorless.
What is colour of chromate ion?
The color of chromate ion is yellow.
What flame colour does copper chloride give?
Flame colours depend on just the metal ion. All copper compounds give the same colour, green.
Which element is responsible for the yellow color of potassium chromate?
The yellow color of potassium chromate is due to the presence of the chromate ion (CrO4^2-). This ion absorbs light in the blue region of the spectrum, leading to the perception of a yellow color.
Which ion is responsible for the colour that has observed in the copper2 solution?
sulphate
Which ion is responsible for the color of a salt- how do you determine this?
p and d block elements with colour
Solution contains metallic ion blue in colour flame test produce blue green colour The solution forms a precipitate when sodium hydroxide is added to the solution What is the ion in the solution?
The metallic ion in the solution is likely copper(II) ion (Cu^2+). This is based on its blue color in a flame test, which gives a blue-green flame, and the formation of a blue precipitate when sodium hydroxide is added, indicating the presence of Cu(OH)2.
What is the ion responsible for the color change when adding copper sulfate to ammonium hydroxide?
The deep blue colour of the resulting solution is due to the cuprammonium ion, more formally the hexaamminecopper(II) ion. Its formula is [Cu(NH3)6]2+ where the numbers inside the brackets should be subscripts, and the 2+ should be a superscript.
Which ion is responsible for the colour that is observed in the CuCl2 solution?
CuCl2(s) = Cu^2_(aq) + + 2Cl^-(aq) In solution the chloride anions )Cl^-) are colourless ; see also dissolved common salt (NaCl) So it must be the copper cations (Cu^2+) that gives the colour blue.
Why does the water colour change to blue when copper sulphate was added?
Anhydrous copper(II) sulphate is white. When added to water, it forms a solution of CuSO4(aq) which is blue because of the Cu2+ ion, which is itself a transition metal ion.
What is the colour of chloride ion?
Chloride ion is colorless.
Is there any noticeable correlation between the metal ion radius and the colour or lack of colour of the ion in solution?
no
What is colour of chromate ion?
The color of chromate ion is yellow.
What is the phenomenon responsible for bluish colour of water in deep sea?
Water is blue because it reflects that wavelength of light.
Is blue a cold colour?
Purple is a cold colour.. and my favourite!
What is the colour of copper ion?
Cu 2+ is blue. Cu2O is reddish; CuO is black, I think.
