Want to know:
C2H3COOH(aq)+H2O(l)⇄H3O+(aq)+C2H3COO−(aq)pKa=4.25The weak acid ionization equilibrium for C2H3COOH is represented by the equation above. A student measures the pH of C2H3COOH(aq) using a probe and a pH meter in the experimental setup shown. Based on the information given, which of the following is true?A[C2H3COOH]>[C2H3COO−][C2H3COOH]>[C2H3COO−] since the pKapKa of the weak acid is less than pKwpKw.B[C2H3COOH]>[C2H3COO−][C2H3COOH]>[C2H3COO−] since the pKapKa of the weak acid is greater than the pHpH of the solution.C[C2H3COOH]<[C2H3COO−][C2H3COOH]<[C2H3COO−] since the pKbpKb for C2H3COO−C2H3COO− is less than pKwpKw.D[C2H3COOH]<[C2H3COO−][C2H3COOH]<[C2H3COO−] since the KbKb for C2H3COO−C2H3COO− is less than the KaKa for C2H3COOHC2H3COOH.
