Hey I got this question wrong
on my physics test so if you could help me find the right answer
and describe how you got it that'd be great. Thanks!

Hello. I was trying to do the question but i think my direction is
wrong. Can you help me to solve it please.
a) Titration of Borax Pipette accurately 10.0 cm of the mixed solution into a 200 or 250 cm conical flask and then add a few drops of methyl red (colour change for this indicator is from red in acid to yellow in basic solution) or screened methyl red indicator. Place this flask on a white, glazed plate...
