A) \[N{{a}_{2}}C{{O}_{3}}+CaC{{O}_{3}}\]
B) \[N{{a}_{2}}C{{O}_{3}}+CaC{{O}_{3}}+silica\]
C) \[silica+N{{a}_{2}}C{{O}_{3}}\]
D) \[silica+borax\]
Correct Answer: B
Solution :
A mixture of silicates of sodium and calcium obtained by heating sodium carbonate, calcium carbonate and silica at about\[1700K\], is called ordinary glass or soda glass. \[N{{a}_{2}}C{{O}_{3}}+Si{{O}_{2}}+CaC{{O}_{3}}\xrightarrow{1700K}\] \[\underset{ordinary\,\,glass}{\mathop{N{{a}_{2}}Si{{O}_{3}}\cdot CaSi{{O}_{3}}}}\,\cdot 4Si{{O}_{2}}+C{{O}_{2}}\]You need to login to perform this action.
