Consider the following indicators and their pH ranges:
Methyl orange
3.2-4.4
Methyl red
4.8-6.0
Bromothymol blue
6.0-7.6
Phenolphthalein
8.2-10.0
Alizarin yellow
10.1-12.0
Assume an indicator works best when the equivalence point of a titration comes in the middle of the indicator range. For which of the following titrations would methyl red be the best indicator?


0.100 M HNO3 + 0.100 M KOH
0.100 M aniline (Kb = 3.8 × 10–10) + 0.100 M HCl
0.100 M NH3 (Kb = 1.8 × 10–5) + 0.100 M HCl
0.100 M HF (Ka = 7.2 × 10–4) + 0.100 M NaOH
0.100 M acetic acid (Ka = 1.8 × 10–5) + 0.100 M NaOH

Did you know?

Hippocrates noted that blood separates into four differently colored liquids when removed from the body and examined: a pure red liquid mixed with white liquid material with a yellow-colored froth at the top and a black substance that settles underneath; he named these the four humors (for blood, phlegm, yellow bile, and black bile).

Did you know?

Congestive heart failure is a serious disorder that carries a reduced life expectancy. Heart failure is usually a chronic illness, and it may worsen with infection or other physical stressors.

Did you know?

Cytomegalovirus affects nearly the same amount of newborns every year as Down syndrome.

Did you know?

Certain rare plants containing cyanide include apricot pits and a type of potato called cassava. Fortunately, only chronic or massive ingestion of any of these plants can lead to serious poisoning.

Did you know?

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
