For the preparation of hydrochloric acid in the laboratory:
What arrangement is done to dissolve hydrogen chloride gas in water?
Name an element which reacts with hydrogen to form a compound which is strongly acidic in water.
Explain why dilute hydrochloric acid cannot be concentrated by boiling beyond 22.2%.
What must be added to sodium chloride to prepare hydrogen chloride?
Give a chemical test to distinguish between the following pair of compounds:
Sodium chloride solution and sodium nitrate solution.
Give a chemical test to distinguish between the following pair of compounds:
Hydrogen chloride gas and hydrogen sulphide gas
Identify the salts P and Q from the observation given below:
When dilute HCl is added to a salt Q, a brisk effervescence is produced and the gas turns lime water milky. When NH4OH soltion is added to the above mixture (after adding dilute HCl), it produces a white precipitate which is soluble in excess NH4OH solution.
Write observation:
A small piece of zinc is added to dilute hydrochloric acid.
State which of the two - a solution of HCl in water or in toluene is an electrolyte. Explain.
