#"LEO SAYS GER"#. #"Loss of electrons: OXIDATION"#.
#"Gain of electrons: REDUCTION"#

Your reaction is NOT a redox process.

Explanation:

For #H_2S(aq) + 2NaOH rarr Na_2S(aq) + 2H_2O(l)#, there is not electron transfer. This is an acid base reaction, not a redox process.

Sulfur is #S^(-II)# in both acid and in the salt. Hydrogen ion is not reduced to dihydrogen gas. I think you should review the assignment of oxidation numbers.
