Question

In the reaction:

CO3²- + H+ --> HCO³-
The CO3²- ion is considered a base because it
1) accepts a proton
2) accepts an electron
3) donates a proton
4) donates an electron
Thanks! :)

Answer 1

1) accepts a proton

Step-by-step explanation:

CO₃⁻² is a base here because it is accepting a proton ( H⁺) through coordinate bonding by donating a pair of electron .

So option (1) is correct .
