Question

A mixture of Hydrogen gas and Carbon (IV) oxide are passed through Potassium hydroxide solution as shown below.

1. State the observation made in the conical flask. 
2. Write the equation for the reaction that takes place in:-
   • the conical flask 
   • the burning of gas x 

Answer 1

1. State the observation made in the conical flask. 
   • Bubbles are observed 
2. Write the equation for the reaction that takes place in:-
   • the conical flask 
     CO_2(g)+2KOH_(aq)→K₂CO_3(aq)+H₂O_(l) 
   • the burning of gas x 
     2H_2(g)+O_2(g)→2H₂O_(g)
