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.

What is the color of precipitate when CuO plus HCl?
light blue color
What color is HCl?
HCl is a colourless gas, with pungent odour. When dissolved in water to form hydrochloric acid , it remains colourless.
Color of zinc granules after reaction with dilute hcl?
Black
What is the change in color of zinc granules when it reacts with HCL?
Black ^^
A 0.5895g sample of impure magnesium hydroxide is dissolved in 100.0ml of a 0.2050M HCl solution the excess acid then needs 19.85ml of 0.1020M NaOH for neutralization calculate the percentage by mas?
To calculate it must be certain that the impurities do NOT react either with HCl or NaOH; hence they shouldn't be acidic or base compounds.
Is HCl a pure compound?
Well that is somewhat loaded it is pure in and of itself, it can be impure but it can be pure. Adding other gasses to it (its a gas at room temp when not dissolved in water to make the acid) would make it impure. Adding things to the acid which do not react could also be seen as impurities. Bear in mind there is no way to make the actual molecule impure by say making HOCl because this is no longer HCl but a different compound (hypochloric acid)

What does nacl hcl kscn reaction gives and what is the color of the product?
I'm not sure what happens when you add nacl, but kscn and hcl reacts to from an intensely red color in the presence of iron.

What is the color of phenolphthaline in dilute HCl?
it is colour less only b`coz the colour of phenolpthaline is pink then we dilute in hcl and hcl is colour less that`s why it is colour less

Why dry HCL is not acidic in the presence of water?
dry HCl is not ionic in nature... The litmus turns its color in the presence of acid(H+) but the dry HCl exist as the molecular compound. The water turns it into ionic therefore such happens...
What is a impure substance?
An impure substance contain impurities; for example polluted water is an impure substance.
How do you dye color in onyx stone?
A treatment with HCl solution or H2SO4 may be useful.
