Cl^(-) আয়নের 0.0018 % (w/v) দ্রবণের 100 মিলি ন্যূনতম ঘনত্ব Cl ^(-) আগে...

100 ml of 0.0018 % (w/v) solution of Cl^(-) ion was minimum concentration Cl ^(-) required to precipitate a negative sol in one h. The coagulating value of Cl ^(-) ion is _______________ (Nearest integer)

[Cl^(-)] in a mixture of 200mL of 0.01 M HCl and 100 mL of 0.01 M BaCl_(2) is

50 mL solution of BaCl_(2) (20.8% w//v) and 100 mL solution of H_(2)SO_(4) (9.8% w//v) are mixed (Ba = 137, Cl = 35.5, S=32) BaCl_(2) + H_(2)SO_(4) rightarrow BaSO_(4) darr 2HCl Weight of BaSO_(4) formed is:

At 298 K, the standard reduction potentials are 1.51 V for MnO_(4)^(-) | Mn^(2+), 1.36 V for Cl^(2) | Cl^(-) , 1.07 V for Br_(2)|Br^(-), and 0.54 V for I_(2)|I^(-) . At pH=3, permanganate is expected to oxidize ((RT)/(F) = 0.059V) :

The standard potential of the cell reaction Zn + Cl_(2) rarr Zn^(2+) + 2Cl^(-) is 2.10"V" . Then the emf of the cell Zn|Zn^(2+)(0.05 M) || Cl^(-1)(0.2"M")|Cl_(2), Pt would be

500 ml of 2M AlCl_(3) solution is mixed with 200 ml of 58.5 % w//v NaCl solution and 300 ml of 50% w//w BaCl_(2) solution (d=2.08 g//ml) . Calculate molarity of Cl^(-) in the final solution.
