is H2CO3+2LiOH=Li2CO3+2H2O a oxidation reduction reaction??

no

right. It is not.

To determine if the given reaction is an oxidation-reduction reaction, we need to check if there is a transfer of electrons between the reactants.

In the given reaction:

H2CO3 + 2LiOH = Li2CO3 + 2H2O

H2CO3 (carbonic acid) is a neutral compound, and LiOH (lithium hydroxide) is also a neutral compound. In this case, there is no change in the oxidation states of any elements or ions. Therefore, there is no transfer of electrons between the reactants, indicating that this reaction is not an oxidation-reduction reaction.

To determine if a reaction is an oxidation-reduction reaction, you can follow these steps:

1. Identify the oxidation states or charges of each element or ion in the reaction.
2. Compare the oxidation states or charges of the elements or ions in the reactants and products.
3. If there is a change in the oxidation state or charge, then it is an oxidation-reduction reaction.

In this case, since there is no change in the oxidation states or charges, the reaction is not an oxidation-reduction reaction.
