2 drops of AgNO3 were added to 4 drops of NaCl,white ppt formed,then 4 drops of KI were added to the above mixture,ppt changed to pae yellow,,why was therea colour change?????how does the colour change explain ksp values for AgCl and AgI ?
why is it when ionic product of a dissociating compound greater than the ksp value,,ppt forms or why when less than the ksp value ppt dissolves?????????

AgNO3 + NaCl => AgCl(white ppt) + NaNO3
AgNO3 + KI => AgI( yellow ppt) + KNO3
there is a change of color because AgI is produced

this question is trivial. by making use of assist you to intend, I presume do it for you. Ksp = [A][B]/[AB] the place given the reaction A + B ? AB and the place [X] is the molar concentration of species X. So, DO. THE. MATH. or is addition, subtraction multiplication and branch too complicated for you, honey?
