Furoic acid 1HC5H3O32 has a Ka value of 6.76 * 10-4 at 25
Chapter , Problem 17.85(choose chapter or problem)
Furoic acid 1HC5H3O32 has a Ka value of 6.76 * 10-4 at 25 C. Calculate the pH at 25 C of (a) a solution formed by adding 25.0 g of furoic acid and 30.0 g of sodium furoate 1NaC5H3O32 to enough water to form 0.250 L of solution, (b) a solution formed by mixing 30.0 mL of 0.250 M HC5H3O3 and 20.0 mL of 0.22 M NaC5H3O3 and diluting the total volume to 125 mL, (c) a solution prepared by adding 50.0 mL of 1.65 M NaOH solution to 0.500 L of 0.0850 M HC5H3O3.
