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 which produces a 1.55m solution is 5.37 × 10⁻⁴.

An acid that may donate simplest one proton is known as monoprotic acid, while polyprotic acid can donate multiple proton. In addition, a monoprotic base can be most effective to accept one proton, while a polyprotic base can take delivery of more than one proton.

The key difference among diprotic and monoprotic 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 solutions.

Calculation

The value of dissociation constant of acid is given as,

Ka = (0.00295)(0.00295)/0.0162)

Ka = 5.37 × 10⁻⁴
