Enough of a monoprotic acid is dissolved in water to produce a 1.55 M solution. The pH of the resulting solution is 2.70. Calculate the [tex]K_a[/tex] for the acid.

Answer :

The ka for the monoprotic acid is 5.37 × 10⁻⁴.

Consequently, a monoprotic acid is an acid that may donate simplest one proton, whilst polyprotic acid can donate multiple proton. in addition, a monoprotic base can most effective accept one proton, while a polyprotic base can take delivery of more than one proton.

The key difference among monoprotic and diprotic acid is that monoprotic acids are able to donate one hydrogen atom or proton to their aqueous solution, while diprotic acids are able to donate hydrogen atoms or protons to their aqueous answer.

Calculation:-

The value of dissociation constant of acid is

Ka = (0.00295)(0.00295)/0.0162)

Ka = 5.37 × 10⁻⁴
