Identify the correctly matched pairs
i. \(\quad \mathrm{TiO}\) - pigment industry
ii. \(\mathrm{MnO}_2\) - dry battery cells
iii. \(\mathrm{Cu} / \mathrm{Ni}\) alloy - UK 'copper' coins
- A i, ii, iii
- B ii, iii only
- C i, ii only
- D i, iii only
Answer & Solution
Correct Answer
(C) i, ii only
Step-by-step Solution
Detailed explanation
\(\mathrm{TiO}\) is a white pigment used in coating industries. \(\mathrm{MnO}_2\) is used in dry battery cells as it possesses good energy. The traditional UK copper coins are mainly made of \(\mathrm{Cu}\), \(\mathrm{Zn}\) and \(\mathrm{Sn}\). Thus, Statement (iii) is…
