CN- ion may be determined by a complexometric titration with silver nitrate
that uses a color indicator to detect the endpoint.
if 20.00ml of a 0.100M solution of silver nitrate is requires to titrate
a 5.00ml aliquot of a CN- solution. the concentration of the original CN-
solution is ???
a.0.100M
b.0.200M
c.0.400M
d.0.800M
e.1.60M
