Question

A sodium salt when react with dil. h so produce acidic gas which have reducing property but not have oxidising property. sodium salt is

(a) na co
(b) na so
(c) na s o
(d) na s

Answer 1

The sodium salt that produces an acidic gas with reducing properties but not oxidizing properties when reacted with dilute H2SO4 is sodium sulfide (Na2S), which forms hydrogen sulfide (H2S) gas.

Step-by-step explanation:

The student's question is asking to identify a sodium salt that produces an acidic gas with reducing properties when it reacts with dilute sulfuric acid (H2SO4), but this gas should not have oxidizing properties. The answer to this question is (d) Na2S, which stands for sodium sulfide.

This compound, when reacted with dilute H2SO4, produces hydrogen sulfide (H2S), a gas with acidic and reducing properties but not oxidizing properties. The other compounds are sodium carbonate (Na2CO3), sodium sulfate (Na2SO4), and sodium thiosulfate (Na2S2O3), which do not produce the required type of gas when reacted with dilute sulfuric acid.
