Find the incorrectly matched pair?
Column $-I$ (ores) $-$ Column $-II$ (metals)
A
sylvine $-$ Potassium
B
Malachite $-$ Magnesium
C
Cinnabar $-$ Mercury
D
Fluorite (Flourspar) $-$ Calcium
Solution
As we know, the correct match is:
Sylvine $KCl$
Malachite $Cu ( OH )_2 \cdot CuCO _3$
Cinnabar $HgS$
Fluorite $CaF _2$
So, only $B$ is not correct. Its correct match is Copper.
