Write balanced complete ionic equation for hcl(aq)+lioh(aq)→h2o(l)+licl(aq) express your answer as a chemical equation. identify

Svet_ta [14]

Explanation:

An equation is said to be balanced when the number of atoms on both reactant and product side are equal in number.

Whereas an equation where electrolytes in an aqueous solution are represented as dissociated ions is known as an ionic equation.

For example, $HCl(aq) + LiOH(aq) \rightarrow H_{2}O(l) + LiCl(aq)$ can be represented in ionic form as follows.

$H^{+} + Cl^{-} + Li^{+} + OH^{-} \rightarrow H_{2}O(l) + Li^{+} + Cl^{-}$

Now, cancelling the common ions present on both sides of the equation. The resulting, ionic equation will be as follows.

$H^{+} + OH^{-} \rightarrow H_{2}O(l)$
