The net ionic equation for the reaction of aluminum sulfate and sodium hydroxide contains which of the following species?

Question

Quizplus · Accepted Answer

The balanced chemical equation for the reaction of aluminum sulfate and sodium hydroxide is:

Al2(SO4)3 + 6NaOH → 2Al(OH)3 + 3Na2SO4

To write the net ionic equation, we first need to identify the soluble ionic compounds that dissociate in water. In this case, the soluble compounds are:

Al2(SO4)3 → 2Al3+ + 3SO42-
6NaOH → 6Na+ + 6OH-

Next, we can combine the ions that appear on both sides of the equation to write the net ionic equation:

2Al3+ + 6OH- → 2Al(OH)3

Thus, only the species involved in the reaction, Al3+ and OH-, are present in the net ionic equation.

Choice C represents the correct net ionic equation, with 3OH- on each side to balance the charge.
