Our chemistry teacher has taught us the in NaHCO₃ bicarbonate form infinite chain due to hydrogen bonding and kHCO₃ carbonate form a dimer anion whats the difference between KHCO₃ and NaHCO₃'s bicarbonate ion? Is this chain and dimer formation happens in water or it could also happens in solid and gas forms?
And I have also a little confusion that i could tell which type of hybridisation happening in a particular molecule but i cant tell if hybridisation happend or not? I cant differentiate between hybridisation atom and non hybridised atom. Thank you for your help and english is not my first language if you didnt understand some bit

It is a matter of crystalisation. Pottasium is bigger then sodium.
This chain is formed only in solid compound. In solution we have enough water to destroy it by hydrogen bonds to it.

Hybridisation takes place, of enough free orbitals present and electrons can move.

Standard: s-Orbital with 2 electrons and 3 p-Orbital with 2 electrons and one free orbital move to sp3, all 4 orbitals are equal.

Hydrogen bonding is a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom. It results from the attractive ...
