What is the balance chemical equation for H2SO4 with NaOH?

Answer 1

__H2SO4(aq)+ __NaOH(aq)=?

H2SO4 is a strong acid, and NaOH is a strong base. Those facts you just have to memorize. There aren't a lot of strong acids and bases, so it's easy to remember them. Strong acid means that the substance completely dissociates in aqueous solution, so in water, H2SO4 exists as two species, H+ and HSO4-. HSO4- is a weak acid, so it will exist in three species, HSO4- H+ and SO4-2. As a strong base, NAOH will completely dissociate in water, meaning it exists as Na+ and OH-.

Acid/base neutralization reactions always produce a salt and water. The ionic equation is:

_H+(aq)+_SO4-2(aq)+ _Na+(aq)+_OH-(aq)=__H2O(l)+_Na2SO4(s)

2H+(aq)+SO4-2(aq)+2Na+(aq)+2OH-(aq)=2H2O(l)+Na2SO4(s)

This is also the net ionic because there is no species on the left side of the equation that remains the same on the right side of the equation.

It can also be written:

H2SO4(aq)+ 2NaOH(aq) = 2H2O(l) + Na2SO4(s)

Answer 2

It's already balanced, the way you've written it. .

The sodium in the sodium peroxide displaces the hydrogen in the hydrogen sulphate, leaving sodium sulphate and hydrogen peroxide. No balancing needed.
