Question

Na2SO4 должно получиться H2SO4

Answer 1

Na2SO4+2HCl=2NaCl+H2SO4

Answer 2

Chemical equation: Na2SO4 + H2O → 2NaOH + H2SO4

Explanation: When sodium sulfate (Na2SO4) reacts with water (H2O), it undergoes a hydrolysis reaction leading to the formation of sodium hydroxide (NaOH) and sulfuric acid (H2SO4).

In this reaction, the water molecule breaks up into its constituent ions, H+ (hydrogen ion) and OH- (hydroxide ion). At the same time, the sodium sulfate molecule dissociates into two sodium ions (Na+) and one sulfate ion (SO4^2-). The hydrogen ion (H+) from water combines with the sulfate ion (SO4^2-) to form sulfuric acid (H2SO4). This is represented in the equation by the formation of H2SO4 on the right side.

Along with the formation of sulfuric acid, the hydroxide ion (OH-) from water combines with the sodium ion (Na+) from the sodium sulfate to form sodium hydroxide (NaOH). This is also represented in the equation by the formation of 2NaOH on the right side.

So, when sodium sulfate reacts with water, it generates sulfuric acid (H2SO4) along with sodium hydroxide (NaOH).
