Calculate the concentration of formate in a 100mm solution of formic acid at ph 4.15. the pka for formic acid is 3.75

The molarity of formic acid is 100 mM or . The dissociation reaction of formic acid is as follows:

The expression for dissociation constant of the reaction will be:

Rearranging,

Here, pH of solution is 4.15 thus, concentration of hydrogen ion will be:

Similarly, thus,

Putting the values,

Therefore, the concentration of formate will be 0.2511 M.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
