how manu mL of 5.00 M NaOH solution are needed to prepare 750mL of a 0.150 M NaOH solution? and how many mL of water misy be added to prepare the above solution?

Expert Solution

We have to prepare diluted solution of NaOH ( 0.150 M ) from stock solution of NaOH ( 5.00 M ) . We can calculate volume of stock solution required to prepare dilute solution of NaOH by using dilution formula.

We have dilution formula, C _stock V _stock = C _dilute V _dilute

V _stock = C _dilute V _dilute / C _stock

V _stock = 0.150 M 750 ml / 5.00 M

V _stock = 22.5 ml

To get 0.150 M NaOH solution , dilute 22.5 ml of 5.00 M NaOH to 750 ml by using distilled water.

Volume of water required to prepare 0.150 M NaOH solution = 750 ml - 22.5 = 727.5 ml

ANSWER : 727.5 ml water is required to add to 22.5 ml of 5.00 M NaOH solution to get 750 ml of 0.150 M NaOH solution.

You prepare a diluted NaOH solution by adding 15 mL of 3 M NaOH to 435 mL of distilled water and stir for several minutes. In a clean dry beaker you obtain about 75 mL of standardized HCl and record the molarity. You take two burets, rinse one with the standardized HCl and one with the diluted NaOH solution. Fill one buret with the HCl and the other with NaOH. Prior to the titration the standard HCl soltion (~15.00 mL)...
