Here is the answer for the question – Assume that you carry out the following dilutions. You’ll find the correct answer below
Assume that you carry out the following dilutions
i) you take 1mL of 10^-6M of AsCl3 and diluted it to 1 Kiloleter (Solution A)
(ii) Then you take 1microliter of Solution A and dilute to 10L to make solution B
(iii) Then you take 1mL of Solution B and dilute to 1L to make Solution C.
Calculate the conc in solution c
The Correct Answer is
CfVf = CiVi (1×10^-3L)(10^-6mol/L) / (1 x 10^3) = 1 x 10^-12 mol/L(1×10^-6L)(1 x 10^-12 mol/L) / (10L)= 1 x 10^-19 mol/L (1×10^-3L)(1 x 10^-19 mol/L) / 1L = 1X10^-22 mol/L
Reason Explained
CfVf = CiVi (1×10^-3L)(10^-6mol/L) / (1 x 10^3) = 1 x 10^-12 mol/L(1×10^-6L)(1 x 10^-12 mol/L) / (10L)= 1 x 10^-19 mol/L (1×10^-3L)(1 x 10^-19 mol/L) / 1L = 1X10^-22 mol/L is correct for Assume that you carry out the following dilutions
