Question

In this activity you will use the virtual lab to determine the concentration of a strong monoprotic acid. To do this, you can perform a titration using NaOH and phenolphthalein found in the virtual lab. (Note: The concentration of the acid is between 0.025M and 2.5M so you will need to dilute the NaOH solution so that the volume to reach the endpoint is between 10 and 50 mL). Once you have determined the concentration of the acid, please enter your answer into a form at the bottom of this page.

my main question here is how much do i need to dilute the 10 M of NaOH woth water in a flask to get the new molarity needed to complete this experiment?( ive already mixed 25 ml of the unknown acid with 0.5 ml of the indicator in the volumetric flask)

Answer 1

coluna given that the aud concentration is in between 0.025m D 2.5 to and you have taken 25 mL of aud. suppose Should using aud concentration is hear about prepare a solution of Naon Formula, I miri = M2 V2 0.025m then you with 0.025 m. prepare you hire 250ml volumetric flask then 250 m, 0.025 m Naon solution; mix = M2 V2 = 0.025 X 250 ml 10 XV, | V = 0 ) 15 X 250 I v = 0.625 mL] if the acid concentration is about 2.5 m then you should prepair a S604-jen , аби шии, 2-5 м. 1 Volyne = 750ml. min = M2 V2 10mxv = 2.5 m X 250ml. Iv = € 62.5 mL) add 62.5 mL lom naoh in some velume the flask and dilute with distilled water upto the mark. CS Scanned with CamScanner
