In the procedure to make different dilutions of 0.01, 0.001, 0.0001 and 0.00001

Question

In the procedure to make different dilutions of 0.01, 0.001, 0.0001 and 0.00001 from 0.10 M NaOH stock solution I should (select one or more answers) use two different graduated cylinders to deliver either NaOH or H_2O (not cross contaminating by using only one) Use a 10-mL graduated cylinder since the concentrations are only given to one significant figure Use 1.00 mL pipet and 9.00 mL pipet to deliver the most accurate volumes Add two drops of indicator to the 0.01M solution before the next dilution (but not any more afterwards) Pour 1.0 mL of 0.10 M NaOH directly into my graduated cylinder

Explanation / Answer

Correct options are :

use two different graduated cylinder to deliver either NaOH or H2O

use 1mL pipet and 9mL pipet

Add two drops of indicator to the 0.01 M solution before the next dilution
