(3) Observe the reaction carefully and answer the questions given below:
NH3 + HCl + NH4Cl
(i) What type of a reaction is this?
(ii) What is the product formed?
(iii) What are the initial and final states of the product so formed?
Answers
Answer:
(i)combination reaction
ii)ammonium chloride
iii)NH3-GAS
HCl-liquid
nh4cl-solid
Answer:
i) A combination reaction (also known as a synthetic reaction) is a reaction in which two or more elements or compounds (reagents) combine to form a single compound (product). These reactions can be represented by equations as follows: X + Y → XY. Our equation NH3 + HCl = NH4Cl is of the same form, so it is a combination reaction.
ii) The product formed is NH4Cl, called Ammonium chloride. It is used as a systemic acidifier in the treatment of severe metabolic alkalosis, in the oral acid load test for the diagnosis of distal renal tubular acidosis, to maintain urine at an acidic pH in the treatment of certain disorders of the urinary tract.
iii) The initial States of reactants are
NH3 (Ammonium) - Gas
HCL (Hydrogen chloride or Hydro chloric acid) - Liquid
The final States of product formed in the reaction is:
NH4CL (Ammonium Chloride) - Crystalline solid
