Question 10

F

A student adds sodium hydroxide solution to dilute sulfuric acid until the mixture is exactly neutral.

Which ions are mainly present in the neutral solution?

[1]

A

$H+\mathrm{H^{+}}$ and $OH−\mathrm{OH^{-}}$

B

$H+\mathrm{H^{+}}$ and $SO42−\mathrm{SO_{4}^{2-}}$

C

$Na+\mathrm{Na^{+}}$ and $OH−\mathrm{OH^{-}}$

D

$Na+\mathrm{Na^{+}}$ and $SO42−\mathrm{SO_{4}^{2-}}$
