A 0.146 M solution of a monoprotic acid has a percent dissociation of 1.50%. Determine the acid ionization constant (Ka) for the acid. A monocarboxylic acid and its potassium salt were combined in a 2:1 mole ratio and dissolved in water. How might you mathematically define the pH ...
How can you determine dominant species given pKa? A solution of acetic acid (pKa = 4.75) has a pH of 6.75. The ratio of the acid to the conjugate base is. Explain your answer. The pH of a 0.1 \ mol \ L^{-1} solution of acetic acid (CH_3COOH) is 2.87. a) Define Ka for ...
Determine the ratio of the acid to its conjugate base at this point, keeping in mind the volume you need to add to reach the equivalence point. Suppose you needed to add 40 mL to reach the equivalence point. If, at the point when the pH is 5.3, you have added 10 mL, it means you...
Use the buffer equation to determine the pH of an acidic buffer solution, given certain acid-base concentrations. The Henderson-Hasselbalch equation is as follows: pH = pKa + log ([A-]/[HA]), where "pKa" is the dissociation constant, a number unique to each acid, "[A-]" represents t...

To determine the apparent affinity (i.e., potency to activate) of a particular phosphoinositide Logothetis and coworkers established an assay using short chain fatty acids phosphoinositides such diC8(octanoly)-PIP2 (Rohacs et al., 1999, 2003). These short chain phosphoinositide...
Determine the concentration of a solution prepared by diluting 5.0 mL of a stock 2.50 M Ca(NO3)2 solution to 150.0 mL. Give the PH value of sodium chloride. 25 ml of a solution of 0.1 M acetic acid (K_a = 1.5 x 10^{-5}) is...
The concentration of free hydrogen atoms is what determines a solution's acidity or alkalinity. This concentration is measured by pH, a term that originally referred to the "power of hydrogen." Household chemicals that are acidic generally have a sour ta
