What is the effect of dilute HCL on colour of blue litmus?
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.
Why is HCL gas not an acid but HCL aqueous an acid?
HCl gas is not an acid because it does not produce H+ ions in solution when dissolved in water. However, when HCl gas dissolves in water to form hydrochloric acid (HCl aqueous), it dissociates into H+ and Cl- ions, making it acidic.
When dal is treated with HCl what is the colour of the dal?
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.
What is the colour of phenolphthalein after addition of dilute HCl?
The color of phenolphthalein after the addition of dilute HCl is colorless. Phenolphthalein is typically pink in basic solutions but turns colorless in acidic conditions due to the change in pH.
Why HCl is used in flame test?
Hydrochloric acid (HCl) is used in flame tests to clean the surface of the metal ion being tested, removing any impurities that could interfere with the observation of the characteristic flame color produced by the metal ion. HCl also helps in breaking down any complexes that may be present, resulting in a clearer and more distinct flame color.
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
What colour is HCL in solution?
Hydrochloric acid is blue-green to green in solution depending on the concentration.

How do you test purity of khoya?
test for starch- dissolving in water+heating+cooling+3-4 drops of tincture iodine, if present, dark blue colour will appear. test for colour- dissolving in water + HCL ,if metanil yellow colour is present, pink colour will appear.
What is the colour of pH paper of hcl?
On the pH-paper Meck art .9565 the acidic range color is green to red-brick.

Does HCL change its colour of moistened blue litmus paper?
yes, as it is an acid . any acid turns blue litmus paper red .
What is the color of impure HCl?
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.
Why does dry HCl gas does not change the colour of the dry litmus paper?
Hydrogen chloride gas is not an acid, is not in solution and does not donate protons. So, no litmus paper color change.
