What is the ph of a dilute 0.00336 m solution of formic, Ask an Expert

Academics

Old chemists used to obtain formic acid (HCHO2) from crushing up ants and distilling their juices. What is the pH of a dilute 0.00336 M solution of formic acid? Formic acid is monoprotic with a Ka of 1.70 x 10-4. You should use the quadratic equation for this one because the solution is very dilute.

1. pH = 3.12

2. pH = 3.08

3. pH = 3.21

4. pH = 3.19

5. pH = 3.17
