So we plug it into here plus log of this guy over this guy we get 0.07 over 0.05
approximately equals we plug this into our calculator and we get 2.65. So that's our PH. Now let's find using the same PH using the Ka. So remember, our equation for conjugate acid and conjugate base is conjugate acid plus our water gives us conjugate base plus our hydronium ion. So let's write the equilibrium equation for this guy. So, Ka, our acid ionization constant is equal to the concentration of hydronium times the concentration of Pyruvate divided by the concentration of pyruvic acid.
