Upper H superscript plus, plus upper O upper H superscript minus right arrow upper H subscript 2 upper O.
2 upper H superscript plus, plus 2 upper O upper H superscript minus right arrow upper H subscript 2 upper O.
Upper C a superscript 2 plus, plus 2 upper O upper H superscript minus, plus upper S upper O subscript 4 superscript 2 minus right arrow upper C a superscript 2 plus, plus upper S upper O subscript 4 superscript 2 minus, plus 2 upper H subscript 2 upper O.
Upper C a (upper O upper H) subscript 2 plus upper H subscript 2 upper S upper O subscript 4 right arrow upper C a upper S upper O subscript 4 plus 2 upper H subscript 2 upper O.

Answer 1

Answer: The equation Upper H superscript plus, plus upper O upper H superscript minus right arrow upper H subscript 2 upper O represents the correct net ionic equation for the reaction between
`Ca(OH)_(2)` and
`H_(2)SO_(4)`.

Step-by-step explanation:

An ionic equation is defined as the equation where both reactants and products are present in the form of ions.

For example, ionic equation between
`Ca(OH)_(2)` and
`H_(2)SO_(4)` is as follows.

`Ca^(2+) + 2OH^(-) + 2H^(+) + SO^(2-)_(4) \rightarrow Ca^(2+) + SO^(2-)_(4) + 2HOH`

Cancelling the spectator ions then net ionic equation will be as follows.

`2H^(+) + 2OH^(-) \rightarrow H_(2)O`

Thus, we can conclude that the equation Upper H superscript plus, plus upper O upper H superscript minus right arrow upper H subscript 2 upper O represents the correct net ionic equation for the reaction between
`Ca(OH)_(2)` and
`H_(2)SO_(4)`.
