I apologize, but the app is not allowing me to post the other 4 pictures of the thermodynamics chart. But I believe the values are universal. Please help!
Calculating the pH of a salt solution
Calculate the pH at 25 °C of a 0.29M solution of potassium butanoate (KC3H,CO2). Note that butanoic acid (HC3H,CO2) is a weak acid with a pKa of 4.82.
