What is coloured hydroxide?
coloured hydroxides are prepared by adding sodium hydroxides to metal salts eg alluminium,copper,ironalluminium gives a white precipitatecopper sulphate gives a pale blue colouriron gives a brown colour
Why is Mn in MnO4- coloured?
Complex ions are not the only ions that have color in solution. For example, Cu2+ is blue in aqueous solutions but is not a complex ion. That's correct, but you haven't answer the question. Mn and Cu are transition metals that have d-orbitals available. One of the properties of the d-orbitals is that they can unfold and allow electrons to move freely in those unfolded orbitals. The energy the electrons lose is in the visible range of the spectrum, so we see it as colour.
What is the word equation for potassium permanganate when heated?
here is the rection... 2KMnO4 + 3H2SO4 = K2SO4 + 2MnSO4 + 3H2O + 2.5O2 (alkaline) and in other conditions... 6 KMnO4 + 9 H2SO4 → 6 MnSO4 + 3 K2SO4 + 9 H2O + 5 O3 The H2SO4/KMnO4 reaction can also produce the oily Mn2O7, which is unstable and can decompose explosively.
What is the coloured liquid used in thermometers?
Some times red coloured liquid is used but mostly gray coloured liquid is used.
What is the color of hydroxide ion?
There is no such thing as an "OH atom". OH- exists as a negative ion that can form crystalline structures with positive metal ions such as Li+ solutions of which are alkaline. The colour of these compounds depends on the metal, group 1 and 2 metals, to which OH usually coordinates are generally colourless. D block metals tend to form coloured compounds due to splitting in d-orbitals.
Which ion in manganese nitrate is responsible the compounds colour?
Manganese. Transition metal ions exhibit electron transitions between their electron orbitals which absorb light of certain wavelengths, making the compound coloured.
The newest coin dollars are made from?
Assuming United States coins - the golden-coloured dollar coins are Manganese-brass (Cu 88.5%, Zn 6%, Mn 3.5%, Ni 2%)
Which elements do you use to make jewelry?
Transition elements, because of their ability to form coloured compounds due to d-d electronic transitions.
Are transition metals highly coloured?
The transition metals themselves are not particularly highly coloured. Gold is golden, copper is copper but the majority are grey or silver with a greater or lesser degree of shine.The compounds formed by transition metals (as opposed to those of group one and two metals) are highly coloured and as with all metals they all burn with distinctive flame colours.
How can softwoods be coloured?
Softwoods can be coloured by staining.
Why do things look coloured?
why the things look to be coloured
Woman with light-coloured hair?
light coloured
Why some organic compound are coloured in nature?
Some organic compounds are colored because of the presence of specific chemical groups called chromophores. These chromophores absorb certain wavelengths of light, which causes the compound to appear colored. The color of the compound depends on the electronic structure of the chromophore and the wavelengths of light that are absorbed.
