Current Question (ID: 9200)

Question:

$\text{Quick lime is heated with silica to give:}$

Options:

1. $\text{CaSiO}_3$
2. $\text{CaSiO}_4$
3. $\text{CaSiO}$
4. $\text{Ca(SiO)}_3$

Solution:

$\text{HINT: CaO is a basic oxide.}$ $\text{Explanation:}$ $\text{STEP 1:}$ $\text{Quick lime (CaO) combines with silica (SiO}_2\text{) to form slag.}$ $\text{CaO} + \text{SiO}_2 \xrightarrow{\Delta} \text{CaSiO}_3\text{(slag)}$ $\text{STEP 2:}$ $\text{While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of the smelting, and minimizing any re-oxidation of the final liquid metal product before the molten metal is removed from the furnace and used to make solid metal.}$
