the ka of formic acid HCOOH is 1.77 x10^-4 A 0.60 formic aci solution of 0.40 M NAOH.which of the following statements is correct regaring the above titration

Question

a. After adding 60.0 mL of NaOH the pH of the resulting solution is greater than 7

b. After adding 20.0 mL of NaOH, the pH of the resulting solution is calculated as the pH = pKa

c.After adding 40.0 mL of NaOH the pH of the resulting solution is greater than 7

d. The pH of 0.60 M of formic acid solution of 40.0 mL s greater than 7

e. The pH adding 30.0 mL of NaOH, the pH of the resulting solution is equal to the pKb of format ion (HCOO^-)

Answer 1

The question isn't very clear and appears to be missing some important information. I assume you mean 0.60 M formic acid? Also, we will need to know the volume of the 0.60 M formic acid that is being titrated. Is it 40 ml? Your sentences don't make total sense either. So, it's difficult to interpret exactly what is being asked. Please be careful to copy the question EXACTLY as it appears.
