HCl is a colourless gas, with pungent odour.
When dissolved in water to form hydrochloric acid , it remains colourless.
When dal is treated with HCl, the color of the dal may change to pink or red, indicating the presence of tannins in the dal. This color change is due to the reaction between tannins in the dal and the acid in the HCl.
The color of the precipitate formed when copper oxide (CuO) reacts with hydrochloric acid (HCl) is typically black or brown. This reaction produces copper chloride (CuCl2) along with water (H2O).
Dilute HCl turns blue litmus paper red. This is because the HCl solution is acidic, causing a color change in the blue litmus paper indicating the presence of an acid.
Hydrochloric acid (HCl) will turn red litmus paper blue due to its acidic nature. Acidic substances like HCl will react with the red litmus paper, causing it to change color.
Dry HCl gas does not change the color of litmus paper because it does not contain any water molecules to dissociate into H+ ions, which are responsible for the acidic properties that change the color of the litmus paper. Dry HCl gas does not produce any H+ ions when it comes in contact with water-free litmus paper, so there is no color change observed.
incolor
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
When dal is treated with HCl, the color of the dal may change to pink or red, indicating the presence of tannins in the dal. This color change is due to the reaction between tannins in the dal and the acid in the HCl.
The reaction between NaCl, HCl, and KSCN does not directly give any colored products. It typically results in the formation of NaSCN (sodium thiocyanate) and KCl (potassium chloride), with HCl acting as a catalyst. The color of the products is usually white or colorless.
The color of the precipitate formed when copper oxide (CuO) reacts with hydrochloric acid (HCl) is typically black or brown. This reaction produces copper chloride (CuCl2) along with water (H2O).

The product equation for the reaction between HCl (hydrochloric acid) and BTB (bromothymol blue) results in a color change from blue to yellow. The equation is: HCl + BTB (blue) → H+ (colorless) + Cl- + BTB (yellow)
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.
Hydrochloric acid (HCl) is a covalent compound, not ionic. BTB (bromothymol blue) is a pH indicator that changes color based on the acidity or basicity of a solution.
