Two tests are carried out to identify an aqueous solution of X. Test 1 Aqueous sodium hydroxide is added and a blue precipitate is produced. Test 2 Dilute nitric acid is added followed by aqueous silver nitrate and a white precipitate is produced. What is X?

your answer would be “dry”

the right answer is c i just did the question.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
