Question

Which salt is produced when H2SO4 reacts with NaOH? K2SO3 Na2SO4 Na2SO3 K2SO4

Answer 1

Na2SO4 is your Answer.

Answer 2

The salt produced is
`Na_2SO_4`. The reaction between a strong acid and a strong base results in salt and water. Since the base and acid are strong the reaction goes to completion. The balanced equation is:

`H_2SO_4 _(_a_q_) + NaOH_(_a_q_) ==> Na_2SO_4_(_a_q_) + 2H_2O_(_l_)`

In fact this is a neutralization reaction in which
`Na^+` and
`SO_4^-^2` are spectator ions.

`2H^+ _(_a_q_)+ + SO_4^-^2 _(_a_q_) + 2Na^+ _(_a_q_) +2OH^- ==> 2Na^+ _(_a_q_) + SO_4^-^2 _(_a_q_) + 2H_2O _(_l_)`,

If you remove the spectactor ions,
`Na^+` ions and
`SO_4^-^2` on both sides of the equation, then the net ionic equation is,

`2H^+ _(_a_q_) + 2OH^- _(_a_q_) ==> 2H_2O _(_l_)`
