What is the reaction between Na and H2SO4?

Answer 1

There is reaction when more or less concentrated H2SO4 is used on NaCl

(BE VERY CAREFULL, only in laboratory circumstances). HCl (gas!) is toxic and very dangerous.

H2SO4 + NaCl --> HCl(gas) + Na2SO4

Answer 2

Reacting NaCl with hot, concentrated H2SO4 (this doesn't work unless the acid is very concentrated and very hot) produces hydrogen chloride gas (which you immediately dissolve in water to make hydrochloric acid) and sodium bisulfate, which is used primarily to lower pH.

Answer 3

The reaction equation is

NaHCO3 + NaHSO4 --> Na2SO4 + H2O + CO2

Answer 4

Any reaction occur between NaCl and H2SO4.

Answer 5

Na2CO3 + H2SO4 --> Na2SO4 + CO2 + H2O

Answer 6

no reaction
