Iron(II) sulfate typically appears as a pale green or light green solution when mixed with water.
because when in a solution it forms blue crystals creating a blue colour
THE COLOUR of the litmus paper will not change as a salt solution is neutral
Yes, salt mixed in water is a solution. Specifically a homogeneous solution.
It's a solution
No, sugar forms a solution when mixed with water.
Blue and green
I think it depends on the mixtures. When I mixed a store bought solution of iodine (2.5% iodine and 2.5% potassium iodide) in water it was brown. But when I added heavy mineral oil and mixed them, the mineral oil layer was a brilliant pink/purple colour. Really impressive. NR Pure iodine is violet. It can act as an electron acceptor (an acid). When iodine is in a solvent that doesn't donate electrons it stays violet. When it is in water or ethanol the iodine accepts electrons from the oxygen atom which then affects the wavelength of visible light that it absorbs, this means that the colour changes.
What happens when you mix water and calcium chloride?Water colour does not change
Bromine water and NaCl mixed together appears colourless. The only condition which there is a colour is when the bromine water is old (bromine water is basically rum), but under normal conditions, the mixture ought to be colourless.
When mixed, it is a solution. If left to sit, the salt can partially distill out of the solution. If the water is left to evaporate, there will be crystals.
A solution of sodium thiosulfate is produced.
