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.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
