Question

Although CO is neutral gas, yet it shows acidic nature or reaction with: (at high pressure and temperature)

• A. $LiOH$
• B. $Ca{{(OH)}_{2}}$
• C. $NaOH$
• D. $Zn{{(OH)}_{2}}$

Answer 1

Answer: (C)

$NaOH$

Answer 2

Carbon monoxide, under pressure, reacts with $NaOH$ to form sodium formate (a salt). This reaction shows the acidic property of CO. $CO+NaOH\xrightarrow[\text{Pressure}]{\Delta }\underset{\text{Sodium}\,\text{formate}}{\mathop{HCOONa}}\,$
