1. The ka value of lactic acid is 1.38*10^{-4}. What would be the pH at 1M concentration? 2. By writing Henderson hasselback equation, explain how pH is equal to pkA when exactly one half of lactic ac If the pH of a solution of HCl is 4, what is its H3O+ concentration...
How can you determine dominant species given pKa? A solution of acetic acid (pKa = 4.75) has a pH of 6.75. The ratio of the acid to the conjugate base is. Explain your answer. The pH of a 0.1 \ mol \ L^{-1} solution of acetic acid (CH_3COOH) is 2.87. a) Define Ka for ...
7. How To Determine The Acidity Of Compounds That Aren’t on the pKachart One of the keys to using a pKatable is to start byidentifying the key functional group(s) present andbe familiar with their acidities. Two of the molecules below might look a little scary because they are so hug...
Use the equation for the pKa to determine the value of the Ka. The equation for the pKa is pKa = – log(Ka). Therefore, 10 ^ (-pKa) = Ka. If the pKa is 7, then 10 ^ -7 = 1.0 x 10 ^ -7. The value of Ka on the titration graph is Ka = 1.0 x 10 ^ -7. Things Nee...
