A 0.10 M aqueous solution of sodium sulfate, Na2SO4, is a better conductor of electricity than a 0.10 M aqueous solution of sodi
Dvinal [7]

Answer: D) More moles of ions are present in a given volume of 0.10 M Na_2SO_4 than in the same volume of 0.10 M NaCl.

Explanation:

A electrolyte is a solution that dissociates completely when dissolved in water. The ions act as good conductors of electric current in the solution.

More is the number of ions , more will be the conductance and hence the solution will be a better conductor of electricity.

0.10 M aqueous solution of Na_2SO_4 is a better conductor of electricity as it dissociates to give three ions whereas 0.10 M aqueous solution of NaCl dissociates to give two ions only.

Na_2SO_4\rightarrow 2Na^++SO_4^{2-}

NaCl\rightarrow Na^++Cl^{-}

Thus 0.10 M aqueous solution of sodium sulfate, Na_2SO_4 , is a better conductor of electricity as more moles of ions are present in a given volume of 0.10 M Na_2SO_4 than in the same volume of 0.10 M NaCl

1 mole of nacl(s) has a greater entropy than 1 mole of nacl(aq). true or false g
Svetradugi [14.3K]
It  is  false   that  1  mole  of  nacl(s)  has  a  greater  entropy  than   1  mole  of  nacl (aq).  

  this  is  because    nacl(aq)   is  in  aqueous  state  while  nacl(s)  is  in  solid  state.  Nacl(aq)  has  greater  entropy  than  nacl(s)  because    in 
aqueous   state  their   is  increase  in  entropy. the  entropy   of  the  two  ions  in  water  has   greater  entropy  than  the  solid   nacl.
