Want to know:
The weak acid CH3COOH has a pKa of 4.76. A solution is prepared by mixing 500.mL of 0.150MCH3COOH(aq) and 0.0200mol of NaOH(s). Which of the following can be used to calculate the pH of the solution?ApH=4.76+log(0.0200/0.150)=3.88BpH=4.76+log(0.0200/0.0750)=4.19CpH=4.76+log(0.0200/0.0550)=4.32DpH=4.76+log(0.0950/0.0750)=4.86
