1.	Some of the following statements are correct and some are incorrect. i) Both MnS and ZnS are soluble in dil. CH_(3)COOH and HCl ii) On adding of hot dilute acetic acid to a solution of barium oxalate and calcium oxalate only calcium oxalate dissolves. iii) Hg_(2)^(2) on reaction with ammonia solution give a black ppt. iv) Both Hg_(2)Cl_(2) and SnCl_(4) does not respond to chromyl chloride test. The wrong statements are :
Answer» `(i),(III),(iv)` `(ii),(iv)` `(i),(ii)` `(i),(ii),(iii)` SOLUTION :Only ZnS is soluble in `CH_(3)COOH` but not MNS and barium oxalate DISSOLVES in acetic acid.
