Write the Chemical equation for the reaction of each weak acid w/ water. Write the corresponding acidity constant expression.

Answer 1

Unfortunately, you didn't include any of the weak acids that are on your list. I will use acetic acid as an example, and hopefully you'll be able to follow the method for your other weak acids.

Acetic acid = CH₃COOH = HC₂H₃O₂

HC₂H₃O₂ + H₂O ==> H₃O⁺ + C₂H₃O₂^- ... this is the equation for reaction of weak acid with water

Ka = [H₃O⁺][C₂H₃O₂^-] / [HC₂H₃O₂] ... this is the acidity constant expression

Good luck.
