please help with part A and B!

- Collect a 50mL Buret and using your 100mL graduated cylinder 50mL of 0.3MNaOH solution - Using your 100mL beaker collect 40mL of unknown H2SO4 solution - Clean and rinse your buret in the manner shown by your TA. - Fill the buret and record the initial mL volume in your lab notebook. - Using your 25mL graduated cylinder measure out exactly 10mL of H2SO4 unknown and place it into a small Erlenmeyer flask. - Add 2-3 drops of Phenolphthalein indicator to the H2SO4 unknown solution and swirl to mix. - Place the Erlenmeyer flask under the buret and lower the buret so that the tip is just inside of the mouth of the flask. - Open the stopcock on the buret slowly and allow the base to drop into the acid in a slow but steady manner. Stir by svirling the flask continuously. - Continue the titration until you see a light pink colored solution that does not return to clear with stirring. - Record the final mL volume of base in your lab notebook. - Repeat this process twice more. Be sure to slow down your addition of base at the point where you have previously determined the end point (faintest of pink colored solution). What amount of unknown will you use in each titration (mL) ? You are incorrect What is the ratio between the acid and the base being used in the experiment? (mol Acid:Mol Base) = (Eg. 1:1 or 2:1 etc) You are incorrect
