Question

Which equation represents the correct net ionic equation for the reaction between Ca(OH)2 and H2SO4?

H+ + OH - H20
© 2H+ + 20H → H20
Ca2+ + 20H + 2H+ + SO2 - >
1 Ca(OH)2 + H2SO4 → CaSO4 + 2H20
221 + SS

Answer 1

A.) H+ + OH- ––> H2O

Step-by-step explanation:

Answer 2

2H+(aq) + 20H(aq) → H20(l)

Step-by-step explanation:

The reaction between sulphuric acid and calcium hydroxide is a neutralization reaction. Neutralization reaction involves the reaction of hydrogen ions and hydroxide ions to form water. This has been shown in the equation.

The number of water molecules formed depends on the number of moles of hydrogen and hydroxide ions present in the compounds. There are two hydrogen ions in sulphuric acid and two hydroxide ions in calcium hydroxide. Hence, two moles of water is formed.
