WebSo let's go ahead and look at all the possible scenarios for these three things. We're going to start with the simplest possible scenario, which is that pH is equal to pK_a. When pH is equal to pK_a, we're raising 10 to the zeroth power. So anything to the zeroth power is equal to one. Which tells us that this ratio is equal to one. http://clas.sa.ucsb.edu/staff/Resource%20Folder/Chem109ABC/Acid,%20Base%20Strength/Table%20of%20Acids%20w%20Kas%20and%20pKas.pdf spicy garlic parmesan wing sauceWebpKa, Ka, and Acid Strength - YouTube pKa, Ka, and Acid Strength The Organic Chemistry Tutor 5.94M subscribers Join 242K views 4 years ago New Organic Chemistry Playlist This organic chemistry... spicy garlic parmesan chicken wings
