20 g of impure NaCl solution is added to aqueous solution having excess AgNO3. AgCl precipitation is obtained with mass 28.7g. find % purity of NaCl.
 
 
sory corect answer is 58.5 you can approach it by writting the balance chemical eqn {1 mol agcl will be produced by one mol of nacl} so 28.7g of agcl ie;0.2 mol will be produced by 0.2 mol...

as 0.2 moles of agcl is produced it means Chlorine obtained from nacl was also 0.2 moles. this implies 0.2 moles of nacl were present in the impure solution. molesXatomic weight(nacl)= MASS ...

This form of isomerism arises when the counter ion in a complex salt is itself a potential ligand and can displace a ligand which can then become the counter ion. Example: [Co(NH 3 ) 5 SO 4 ...
 
PRAPULPODISHETTI 5 months ago
 
These isomers result from the interchange of ions inside and outside the coordination sphere. For example, the red violet [Co(NH3)5Br]SO4 and the red [Co(NH3)5SO4]Br are ionization isomers....
