Chapter 9: Problem 25

The composition of flint glass is (a) \(\mathrm{SiO}_{2}+\mathrm{Na}_{2} \mathrm{CO}_{3}+\mathrm{CaCO}_{3}\) (b) \(\mathrm{SiO}_{2}+\mathrm{CaCO}_{3}+\mathrm{CuSO}_{4}\) (c) \(\mathrm{SiO}_{2}+\mathrm{K}_{2} \mathrm{CO}_{3}+\mathrm{CaCO}_{3}\) (d) \(\mathrm{SiO}_{2}+\mathrm{K}_{2} \mathrm{CO}_{3}+\mathrm{CaCO}_{3}+\mathrm{Pb}_{3} \mathrm{O}_{4}\)

Short Answer

Expert verified
Answer: (d) \(\mathrm{SiO}_{2}+\mathrm{K}_{2} \mathrm{CO}_{3}+\mathrm{CaCO}_{3}+\mathrm{Pb}_{3} \mathrm{O}_{4}\)

Step by step solution

01

Identify the Lead-containing Compound

In this exercise, we have to find the combination which contains lead (Pb) as an ingredient. This will provide the correct composition for flint glass.
02

Analyze the Options

Let's examine the provided options: (a) \(\mathrm{SiO}_{2}+\mathrm{Na}_{2} \mathrm{CO}_{3}+\mathrm{CaCO}_{3}\): Contains no lead (Pb) (b) \(\mathrm{SiO}_{2}+\mathrm{CaCO}_{3}+\mathrm{CuSO}_{4}\): Contains copper (Cu) instead of lead (Pb) (c) \(\mathrm{SiO}_{2}+\mathrm{K}_{2} \mathrm{CO}_{3}+\mathrm{CaCO}_{3}\): Contains no lead (Pb) (d) \(\mathrm{SiO}_{2}+\mathrm{K}_{2} \mathrm{CO}_{3}+\mathrm{CaCO}_{3}+\mathrm{Pb}_{3} \mathrm{O}_{4}\): Contains lead (Pb) as \(\mathrm{Pb}_{3} \mathrm{O}_{4}\)
03

Choose the Correct Option

Based on our analysis, it is clear that the correct composition of flint glass is the one containing lead (Pb). Thus, the answer is: (d) \(\mathrm{SiO}_{2}+\mathrm{K}_{2} \mathrm{CO}_{3}+\mathrm{CaCO}_{3}+\mathrm{Pb}_{3} \mathrm{O}_{4}\)
