10. when one adds dilute agno; solution to another solution containing equal concentration of ci, br, and t, which is precipitated most? (a) agcl if the hn hana

More the covalent character lesser the solubility.

You must have studied like dissolve like.

AgCl is most ionic among them so most soluble.

AgI is least soluble as it has highest covalent character

I- ion has a largest size and hence has maximum polarisability. So the covalent character of AgI is maximum among others. So as AgI is the most covalent compound and AgNO3 is an ionic compound, AgI dissolves least and is precipitated out first. Then AgBr and finally AgCl. Also the Ksp values of these salts are in the order of AgCl>AgBr>AgI and hence the ionic product of ions reaches AgI first and hence it is precipitated first.

lower solubility product of AgI as compared to other

got this??

how can we relate it with electrochemical series

for ppt ksp or covalent character is sufficient to decide

This is sufficient for solubility and precipitation..

sir how can we relate it to electrochemical series ??

here we will correlate it by polarisation
