Chemistry

If the Ka of a monoprotic weak acid is 6.6×10−6, what is the pHof a 0.29 M solution of this acid?

The Ka of a monoprotic weak acid is 0.00604. What is the percentionization of a 0.114 M solution of this acid?

Enough of a monoprotic weak acid is dissolved in water toproduce a 0.0154 M solution. The pH of the resulting solution is2.38. Calculate the Ka for the acid.

Enough of a monoprotic weak acid is dissolved in water toproduce a 0.0186 M solution. The pH of the resulting solution is2.60. Calculate the pKa for the acid.
