Students have asked these similar questions
. The odor of spoiled butter is due in part to butanoic acid (HC4H7O2) which results from the breakdown of the fat in butter. A 0.100M solution of butanoic acid is 1.23% ionized.
Write the chemical equation for the ionization of this acid in water.
Write the Ka expression for this acid.
What is the equilibrium concentration of each product and the reactant?
Determine the pH of 0.01 M solutions of Citric Acid, Sodium Dihydrogen Citrate, Sodium Hydrogen Citrate, and Sodium Citrate solutions. Citric Acid has pKas of 3.13, 4.76, and 6.40. For situations where this cannot be done with ICE/small-x approximation, list the simultaneous equations you could have a computer program solve to arrive at the answer.
The pH range of a solution can also be determined using indicators. Indicators are molecules
that exhibit different colors over a specific pH range. Examples of indicators and the associated
colors are shown below.
