Chemistry
What do you observe when:
(a) an acid is added to a basic solution?
(b) ammonium chloride is dissolved in water?
Answer
(a) When an acid is added to a basic solution, neutralization reaction takes place and salt and water are produced. For example:
NaOH + HCl ⟶ NaCl + H2O
(b) When ammonium chloride is dissolved in water, heat is absorbed leading to fall in temperature. So the apparatus in which this reaction occurs becomes colder than earlier.
