dry hydrogen chloride chloride gas does not turn blue litmus to red litmus whereas hydrochloric acid does. why?
Answers
dry hydrogen chloride gas does not turn blue litmus paper to red because in dry form the acid does not release H+ ions and litmuspaer only change its colour when contact with ions of acid or base
Answer:
In dry state, hydrogen chloride does not give any hydronium ions. In other words, it does not behave as an acid and does not bring any change in the colour of blue Litmus.
Explanation:
When dry Litmus Paper comes in contact with hydrogen chloride gas, its colour does not change. This means that in the absence of water the gas does not release any hydronium ions. However, when moist Litmus Paper comes in contact with it, the gas slightly dissolves in water to form hydrochloric acid. The acid produces hydronium ions which change blue Litmus into red.
