Question

Calculate the pH of the solution that results from each of the following mixtures.

A. 140.0 mL of 0.27 M HF with 220.0 mL of 0.31 M NaF

B. 170.0 mL of 0.12 M C2H5NH2 with 275.0 mL of 0.20 M C2H5NH3Cl

Answer 1

Answer #1

first to calculate Molarity in total volume.

then to find pH using formula.

Solo - (A) 0.140 L of 0.27 M nF with 0.22 L of 0.31M NaF. Totut volume = 0.140+ 0.22 = 0.36L. ha 10-4 I to calaslabe the mola
