🤓 Based on our data, we think this question is relevant for Professor Daly's class at UD.
We’re being asked to calculate the concetnration of H+ of a 0.1 M propionioc acid
HC3H5O2 is a weak acid that will further react in water to form H3O+
HC3H5O2 (aq) + H2O (l) → H3O+ (aq) + C3H5O2- (aq)
We can use the H3O+ produced to find the pH
A student planned an experiment that would use 0.10 M propionic acid (HC3H5O2 , Ka = 1.4 × 10–5). Calculate the equilibrium concentration of the hydrogen ion in this solution.
A. 2.4 ×10–3 M
B. 8.3 × 10–12 M
C. 1.2 × 10–3 M
D. 5.0 × 10–4 M
E. 1.2 × 10–7 M
