An electrode has a potential of 1.201 V with respect to a saturated silver-silver chloride electrode. What would the electrodes

potential be relative to a saturated calomel electrode (S.C.E.)? E = 0.197 V for the saturated silver-silver chloride electrode and E = 0.241 V for the S.C.E.

Answer:

The potential wrt. calomel is 1.254 V

Explanation:

Given:

Potential wrt. silver chloride E_{Ag}  = 1.201 V

Potential wrt. saturated silver chloride E = 0.197 V

Potential wrt. SCE E_{Hg} = 0.241 V

Now potential wrt. hydrogen is given by,

   = 1.201- 0.197

   = 1.004 V

And we find for potential wrt. calomel,

   = potential wrt. hydrogen + potential wrt. SEC

   = 1.004 +0.241

   = 1.254 V

Therefore, the potential wrt. calomel is 1.254 V

Annette [7]

Answer:  The precipitate formed is BaSO_4

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid or precipitated form are represented by (s) after their chemical formulas.  

A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.  

The balanced chemical equation is:

K_2SO_4(aq)+BaCl_2(aq)\rightarrow BaSO_4(s)+2KCl(aq)
