Salts and Buffers

Salts and Buffers

This webinar on salts and buffers is the second part in our three-part series on acid/base chemistry for the MCAT. You will learn about the three different types of salts, how to identify a buffer system, and how to calculate and predict pH depending on the buffer used. We will focus on the buffer system of the blood.

  • Determine whether a salt is acidic, basic, or neutral

  • Identify and calculate with buffers

  • Predict blood pH based on the buffer system of the blood


Knowledge Fundamentals

  • The three different types of salts

  • The Henderson-Hasselbalch equation

  • Minimize errors in unit conversions


I think these webinars are really helpful! I like how they’re styled like a TED talk, so they don’t interfere with the day, but they’re really helpful review 🙂

I found everything helpful about these webinars: the explanations, the illustrations, just everything!

Amazing material conveyed concisely and in great detail!

The wealth of information and sample questions are great.

“These 30 minute FREE, live videos conducted each Friday helped me get through the pandemic. Weike is an exceptional tutor, and being able to ask questions after she’s done was magnificent. These webinars have even helped me in class subjects such as Biochemistry.  I’m looking forward to starting one-on-one tutoring with Cambridge Coaching, and I’m already feeling confident about taking the MCAT when the time comes.”
