Evolution of Carbon dioxide from Sodium bicarbonate and potassium hydroxide??!

1/2"

Hi!
Here’s a question my teacher asked me to solve about evolution of carbon dioxide,
We know that carbon dioxide is obtained by the action pf dilute acids on any metallic carbonate or bicarbonate e.g.
NaCO ₃ + (dilute) HCl gives( I am using gives since I don’t know how to give an arrow)NaCl + H₂O+CO₂

NaHCO₃ + (dilute) HCl gives 2NaCl + 2H₂O+CO₂ Therefore what would be the result of


NaHCO₃ + KOH ?

Think it “might” be (just out of instinct)
NaHCO₃ + KOH gives NaOH +KOH+H₂O+CO₂:????confused:

I don’t know whether it’s correct or not and I would be very thankful if someone helps!

Lol for some reason I find your equation cute

The hydrogencarbonate ion HCO₃^- can both act as an acid and base. If it receives a proton to become H₂CO₃ (carbonic acid), it acts as a base. If it loses a proton to form carbonate ion CO₃^2-, it acts as an acid.

Anyway this is a standard acid-base neutralization reaction. Write out the individual ionic equations for the acid and base disassociation first.

[tex]KOH -> K^{+} + OH^{-}[/tex]
[tex]NaHCO_{3} -> NaCO_{3}^{-} + H^{+}[/tex]

Next neutralize the H⁺ and the OH^-, and then combine the remaining ions into a salt

For the record: this is not sodium carbonate.
