Although it has been established that a colour sensitiser must dye the silver bromide grain, yet all dyes that stain the silver bromide are not sensitisers. The solutions were continued tested using blue light beam to test the Tyndall effect. Join now. Colours of precipitates help to identify compounds. The sol formed three layers which are water, oil, water, The light was scattered less in upper layer. There are some properties of the colloid that can. Ask your question. For Silver Bromide Sol, a colloidal dispersion of silver bromide was formed immediately. It darkens when light shines on it. The scattered light was obvious seen through the lower layer. Properties. We can decide which ions (cations or anions) are in the compound by comparing colours of different precipitates.
