Question- A solution 25.0 mL NaCH3COO and 10.0 mL 1.0 M CH3COOH has a pH of 5.18. Find the Ka of acetic acid and calculate the pH of the buffer after 2 mL of 1.0 M NaOH are added to the solution.
I need help for above question. Show each steps for the above problem.
A proton in a magnetic field has two spin states, one aligned with the field B and the other anti aligned. the energies of these spin states are E down=hyB/2 and E up =-hyB/2, where y=26.8*10^7 (Tesla)^-1.
The Ka of HNO2 is 7.1 x 10^-4. Use this to find the volume (mL) and pH of 0.0588 M KOH needed to reach the equivalence point(s) in titrations of 28.5 mL of 0.0380 M HNO2.
What is the pH of a solution resulting from the titration of 50 mL of 0.050 M acetic acid solution, CH3COOH, with 50 mL of 0.050 M NaOH solution
