The chemical composition of basic slag is

A. Ca₃(PO₄)₂

B. (CaO)₃P₂O₅, SiO₂

C. (CaO)₂P₂O₅, SiO₂

D. (CaO)₃P₂O₄, SiO₄

Answer: Option B

Solution(By Examveda Team)

Basic slag is low in silica and high in base-forming oxides that are used in the basic process of steelmaking and that are subsequently useful as a fertilizer.
A basic slag contains oxides like MgO and CaO, which makes the slag thicker.
The chemical composition of basic slag is (CaO)₃P₂O₅, SiO₂.
