1.	Statement-1:Baryta water becomes turbid on passing `CO_(2)` gas through it but turbidity becomes clear on passing more `CO_(2)` gas. Statement-2 : Carbonates give yellowish white precipitate with silver nitrate solution.The precipitate becomes yelllow or brown on heating.A. STATEMENT-1 is true, STATEMENT-2 is true and STATEMENT-2 is correct explanation for STATEMENT-1B. STATEMENT-1 is true, STATEMENT-2 is true and STATEMENT-2 is not correct explanation for STATEMENT-2C. STATEMENT-1 is true, STATEMENT-2 is falseD. STATEMENT-1 is false, STATEMENT-2 is true
Answer» Correct Answer - B Statement-1:`Ba(OH)_(2)+CO_(2)toBaCO_(3)darr (white) +H_(2)O, BaCO_(3) + H_(2)O+CO_(2) to Ba(HCO_(3))_(2)` Statement-2:`2Ag^(+) + CO_(3)^(2-) to Ag_(2)CO_(3) darr ("white"),Ag_(2)CO_(3) darr overset(Delta) to Ag_(2)O darr ("brown") +CO_(2) uarr`
