Q. Thomas slag is
A) $CaSiO_{3}$
B) $Ca_{3}\left( PO_{4} \right)_{2}$
C) $MnSiO_{3}$
D) $CaCO_{3}$
Explanation
(b)
Thomas slag is $Ca_{3}\left( PO_{4} \right)_{2}.$ It is used as a fertilizer. It has 14-18% of $P_{2}O_{5}.$
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 6CaO + P_{4}O_{10}\ \longrightarrow 2Ca_{3}\left( PO_{4} \right)_{2}$
phosphatic slag
or Thomas slag
