CO_2 is a gas, while SiO_2 is a solid, but both are

Correct answer: (A) acidic. CO_2 is a gas, while SiO_2 is a solid but both are acidic in nature, both reacts with base and forms carbonate and silicates. CO_2+underset Base NaOH longrightarrow NaHCO_3 underset Base SiO_2+underset BaOH 2 NaOH longrightarrow Na_2 SiO_3+H_2 O

Q19 / 170 · Manipal (MET) 2019 · Chemistry

$\mathrm{CO}_2$ is a gas, while $\mathrm{SiO}_2$ is a solid, but both are

Correct answer
A
acidic
B
ionic
C
discrete molecules
D
covalent containing $\pi$-bonds

Solution

$\mathrm{CO}_2$ is a gas, while $\mathrm{SiO}_2$ is a solid but both are acidic in nature, both reacts with base and forms carbonate and silicates. $\begin{gathered}\mathrm{CO}_2+\underset{\text { Base }}{\mathrm{NaOH}} \longrightarrow \mathrm{NaHCO}_3 \\ \underset{\text { Base }}{\mathrm{SiO}_2+\underset{\text { BaOH }}{2 \mathrm{NaOH}} \longrightarrow \mathrm{Na}_2 \mathrm{SiO}_3+\mathrm{H}_2 \mathrm{O}}\end{gathered}$

Hence, the correct answer is option: 'A'.

$\mathrm{CO}_2$ is a gas, while $\mathrm{SiO}_2$ is a solid, but both are
