Enough of a monoprotic acid is dissolved in water to produce

Enough of a monoprotic acid is dissolved in water to produce a 0.0170 m solution. The ph of the resulting solution is 2.51. Calculate the Ka for the acid.

HA <---> H⁺ + A^-

pH = 2.51

-logH⁺ = 2.51

[H⁺] = 10^-2.51 = 0.0031M = [A^-]

[HA] = 0.0170M - 0.0031M = 0.0139M

Ka = [H⁺][A^-]/[HA]

= 0.0031M*0.0031M/0.0139M

Ka = 6.91*10^-4
