Write equations for the reactions : (i) dil. HCl and sodium thiosulphate. (ii) dil. HCl and lead nitrate soln.
(i) Na2S2O3 + 2HCl ⟶ 2NaCl + SO2 + S + H2O (ii) Pb(NO3)2 + 2HCl ⟶ PbCl2 ↓ + 2HNO3
What property of hydrogen chloride is demonstrated when it is collected by downward delivery [upward displacement]. Why is hydrogen chloride not collected over water.
Hydrogen chloride is 1.28 times heavier than air, hence it is collected by downward delivery [upward displacement]. Hydrogen chloride is not collected over water since it is highly soluble in…
Write equations for the reaction of dil. HCl with each of the following : (i) iron (ii) sodium hydrogen carbonate (iii) iron [II] sulphide (iv) sodium sulphite
(i) Fe + 2HCl ⟶ FeCl2 + H2 (ii) NaHCO3 + HCl ⟶ NaCl + H2O + CO2 (iii) FeS + 2HCl ⟶ FeCl2 + H2S (iv) Na2SO3 + 2HCl ⟶ 2NaCl + H2O…
Give one example of a reaction between the above two gases which produces a solid.
NH3 (g) + HCl (g) ⟶ NH4Cl (s) When a gas jar containing HCl gas in inverted over a jar full of ammonia gas, dense white fumes are formed. These…
Of the two gases, NH3 and HCl, which is more dense. Name the method of collection of this gas.
Hydrogen chloride gas is denser than NH3. Reason — V.D. of NH3 = 8.5 and that of HCl = 18.25 HCl gas is collected by upward displacement of air.
Write a balanced equation for Sodium chloride from sodium carbonate soln. and dilute hydrochloric acid.
Na2CO3 + 2HCl (dil) ⟶ 2NaCl + H2O + CO2 (g)
