Question

The end point of a titration was reached after 22 ml of 0.050 m disodium edta titrant was dispensed into a solution containing the zinc ion. calculate the moles of disodium edta used

Answer 1

moles =molarity x volume in liters

molarity=0.050m

volume in liters = 22/1000=0.022 L

moles is therefore= 0.022 x0.050 =1.1 x10^-3 moles of disodium edta

Step-by-step explanation:

Answer 2

The moles of disodium edta used is calculated using the below formula


moles =molarity x volume in liters

molarity=0.050m
volume in liters = 22/1000=0.022 L

moles is therefore= 0.022 x0.050 =1.1 x10^-3 moles of disodium edta
