- Dry hydrogen chloride gas does not turn blue litmus paper red . . .
Dry hydrogen chloride gas does not turn blue litmus paper red whereas hydrochloric acid does Why? Ans: Hint: HCl is naturally a gas When we make its solution, water is always present as a solvent in less or more amounts Dry hydrogen chloride does
- Dry hydrogen chloride gas does not turn blue litmus red . . .
Dry HCl is in covalent form and does not dissociate to give H+ ions In aqueous solution , HCl dissociate to form the same and changes the litmus colour because it is the H+ ions that are responsible for colour change
- Why does gaseous HCl not change dry blue litmus paper to red?
I found that when blue litmus is near the evolved gas, it doesn't turn red But, when litmus is dipped in water and then brought near the HCl gas it does change to red Why is this happening?
- Explain why dry hydrogen chloride gas does not affect a dry . . .
A dry strip of blue litmus paper is unaffected by dry HCl gas due to the gas’s non-acidic nature In the presence of a drop of water, HCl gas dissolves and produces hydrochloric acid, which turns blue litmus paper red
- Explain why dry hydrogen chloride gas does not affect a dry . . .
Dry hydrogen chloride gas does not contain any ions Due to the absence of hydronium [H 3 O +] ions, it is neutral and does not affect a dry strip of blue litmus paper On the other hand, in the presence of a drop of water, HCl dissolves in it and dissociates into hydronium [H 3 O +] ions and chloride ions [Cl-] HCl + H 2 O H 3 O + + Cl-
- State reason for the following statements : Dry hydrogen . . .
Assertion (A): Hydrogen chloride gas does not change the colour of dry blue litmus paper Reason (R): Hydrogen chloride gas dissolves in the water present in wet litmus paper to form H + ions A Both A and R are true, and R is the correct explanation of A
- State the reason: Dry hydrogen chloride gas does not turn . . .
(a) Tap water conducts electricity, whereas distilled water does not (b) During the summer season, a milkman usually adds a very small amount of baking soda to fresh milk (c) For dilution of acid, acid is added into water and not water into acid
