Question

why lithium and magnesium do not form solid hydrogen carbonates​

Answer 1

Answer:

magnesium hydrogen carbonate is not obtained in solid form, LiHCO3 also cannot be since both have similar properties. Due to the small size of lithium, it will polarize the large anion oxygen, the C−O bond will weaken and Li−O bond will strengthen, they will split, and they will not be in the solid state
