Calculate the pH of a solution prepared by mixing 250 mL of 0.20 M HCl and 270 mL of 0.30 M dibasic potassium phosphate (K2HPO4). The pKa of the phosphoric acid is 6.85. Show all calculations for the following:
1) moles of weak base and its conjugate acid after the neutralization by HCl
2) molar concentration of the weak base and the conjugate acid
3) pH of a buffer
