Why you use titration?
Titration is used to calculate the molarity of an acid or base (standardising), using a base or an acid respectively with a known molarity (primary standard).
What is the use of potentiometric titration?
acid and base use to measure the molarity
Why you use phenolphthalein in titration?
it acts as acid base indicator
How do you calculate the concentration of 10mL of a weak acid in a titration where the strong base has a molarity of 0.09994M and the equivalence volume is 21.20mL?
you have to use titration... http://www.avogadro.co.uk/miscellany/titration/titreset.htm or you can use the formula you have to use titration... http://www.avogadro.co.uk/miscellany/titration/titreset.htm or you can use the formula
What are the best indicator use in titration of weak base against strong acid?
vodka cruisers, the raspberry one.

How do you dilute 30 mL of 12 molar hydrochloric acid to a 0.1 molar hydrochloric acid solution?
in order to dilute the acid, you need to have a good pH meter, a burette, ring stand, burette clamp, and base you want to use. You use the formula Ma * Va = Mb * Vb where Ma is molarity of H+, Va is volume of acid, Mb is Molarity of base and Vb is volume of base. you use that formula to calculate amount of base needed to reach 0.1 molar. to get it exactly right, use a burette and do titration
Can you use indicator other than phenolphthalein in the titration of NaOH?
Yes you can use methyl red, methyl orange, bromophenol blue and other indicators instead of phenolphthalein in the acid-base titration of NaOH.
How do you find concentration of an acid from a titration?
use phenol phtalein as an indicator
Why is it better to use a weak acid rather than a strong acid when you titrate a base?
Because it only partly ionises because it has less H+ ions so the reaction is not as fast, therefore the titration is easier to do becasue you have more time to see when it has reached neutral etc Edit: This answer is entirely incorrect. NEVER use a weak acid or a weak base as the titrant. Doing so will result in the formation of a buffer during the titration, and no useful information can be gained.
What colorimetric pH indicator should you use for ammonia and hydrochloric acid titration?
Since the titration is between a strong acid and a weak base, methylorange should be suitable as the equivalence point is around pH 5. The K of the indicator should be equal to the pH at the end point. Methyl orange is that indicator
What is the indicator used in sulphonic acid titration?
Titration with strong base requires eg. methyl red, changing to yellow at 6.2, but it endpoint may come too early when the sulfonic acid is weaker than acetic acid: OK if pKa < 4.5 .So it's safer to use phenolphaleine (purple at pH=8.5) for acids with pKa < 8
