Before treatment, the samples were exposed to outdoor weathering for different periods of time and then treated with a 5 % solution of pure iron (II) sulphate and commercial iron (II) sulphate. It was determined that the pre-weathering time affected the final colour change, as the samples ...

Is it that even tho its an acid salt, when dissolved in water it is alkaline?? 2. Iron (III) Sulphate I have done a titration with iron(III) sulphate and iron(II) sulphate ( which is colourless if I remember correctly? is it?? please confirm with me... ) Ok I did this some ...
Hydrated iron(II) sulphate is pale green. When it is heated, the crystals first turn white and on stronger heating, a brown residue of iron(III) oxide is formed. During the strong heating two gases are formed. One of the gases removes the colour from acidified potassium manganate(VII). ...
(II) ammonium sulfate to the pale yellow MgHCF NCs suspension (40 μg ml−1) immediately led to a change in the optical absorption and colour from yellow to green and finally blue (Fig.3b). Equilibrium was reached in 30 s. The mixture of MgHCF NCs upon challenge with varying...

Iron binding, naturally occurring protein bovine lactoferrin (bLf) has attracted attention as a safe anti-cancer agent capable of inducing apoptosis. Naturally, bLf exists partially saturated (15-20%) with Fe3+ however, it has been demonstrated that mani
The intensity of the generated colour correlates directly with the number of lysed cells. After the treatment of FeCl3 as indicated in both cells, 25 µL of culture media was added to new 96-well plate followed by the addition of 25 µL of reaction mix from the LDH kit. The ...

In addition to the absolute colour indices the difference colour indices as compared with the type ®Bayferrox 920 (Bayer AG) are also given. The aluminium content of the pigment is 0.14%. Example 2 Same as example 1, but using pure iron sulphate solution. After an oxidising time of ...
