Question
1) A titration is a way to measure the strength of an unknownacid or base. If a weak acid solution is in a beaker and it onlytakes a small amount of an unknown solution to neutralize it, whatcould the unknown solution be?A. strong acid
B. strong base
C. weak acid
D. weak base 2) Acidic solutions containing an indicator have a red color.Blue solutions with the same indicator are basic. If a basesolution is being added into an acid one drop at a time, what colordo you expect one drop before the solution is neutralized?
A. clear
B. red
C. blue
D. purple 2) 1) A titration is a way to measure the strength of an unknownacid or base. If a weak acid solution is in a beaker and it onlytakes a small amount of an unknown solution to neutralize it, whatcould the unknown solution be?

Explanation / Answer
2) I'm assuming the question is asking what color the solutionshould be at the end point, and not the equivalencepoint. At the equivalence point (pH = 7.00), thesolution should be clear. At the end point, the solution should bea light red, or pink, because the solution is still technicallyacidic. The color changes depend on which indicator is used,however.
Hope this helps. :)
