a chemical reaction is taking place
HCl is a colourless gas, with pungent odour. When dissolved in water to form hydrochloric acid , it remains colourless.
we know that hcl is an acid and acids change purple phenolphthalein to colourless. So HCL changes purple phenolphthalein to colourless
Sulfur is normally a yellow mineral, also with a yellow streak. However, there are several allotropes of sulfur. Melting sulfur and then suddenly cooling it again produces a rubbery reddish solid which gradually turns yellow and brittle. Gaseous sulfur is actually bluish. A pale yellow.
Purple:) colourless or pale yellow, but in jaundice its colour is yellow.
the solution turns red and splits into two colours, red on top and yellow on bottom; after standing the top (red) layer turns colourless and opaque but there is no real reaction.

The ethene doesnt change from orange to colourless as ethene is already colourless but the bromine water turns from orange to colourless.
Hydrogen Chloride (HCl) is an acid. Bromothymol blue turns yellow as HCl is placed in it. Acids change the color of bromothymol blue from green-yellow, depending on whether it is a strong acid or a weak acid.

Phenolphthalein turns pink in a base and turns colourless in a base

its react with bromine water or idone and turns the solution colourless. not clear colourless...more scientific..haha
HCl is a gas at room Temperature and if contained in cylinders. The gas i colourless If you mean Hydrochloid acid HCl(aq) then this is a colourless solution which is transported in either glass lined containers or plastic barrels. [ HCl is avalible on the market however can only be sold to licenced premisis for obvious reasons - when concentrated it is highly corrosive. Impure HCl does not really exist, it depends whats in it. If there is a coloured compound such as copper II oxide the colour of the solution will be blue.
it decolourizes it (turns from orange brown to colourless)
Orange. It turns colourless in acids and pink in alkaline.
