Question- What are the concentrations of acetic acid (pKa = 4.76) and acetate in a buffer solution of 0.15 M at pH 4.5? Enter your answer to two significant figures. (For example, 0.0090 and 0.0097 each have two significant figures, whereas 0.009 has only one significant figure.)
Please provide with the balanced reaction.
If one component of a solution follows Raoult's Law subsequently the other component must also obey the same law. Intermolecular forces are small in ideal solutions.
Enough of a monoprotic acid is dissolved in water to produce a 0.0137 M solution. The pH of the resulting solution is 6.48. Calculate the Ka for the acid.
