Match List-I with List-II : Choose the correct answer from the options given below :

  1. (a)-(i), (b)-(iii), (c)-(iv), (d)-(ii)
  2. (a)-(iv), (b)-(ii), (c)-(iii), (d)-(i)
  3. (a)-(ii), (b)-(iv), (c)-(iii), (d)-(i)
  4. (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)

Answer

(2) (a)-(iv), (b)-(ii), (c)-(iii), (d)-(i)

Solution

As per NCERT:

(a) Borax: Na2B4O7 10H2O — (iv)

(b) Kernite: Na2B4O7 4H2O — (ii)

(c) Orthoboric acid: H3BO3 — (iii)

(d) On heating, borax first loses water and swells into a glassy material known as borax bead, a mixture of sodium metaborate and boric anhydride:

Na2B4O7 2NaBO2 + B2O3 ⇒ NaBO2 — (i)

∴ (a)-(iv), (b)-(ii), (c)-(iii), (d)-(i)

Answer: (2)
