What do we use this for? pH is a way to measure the relative strengths of acids and bases. We start this video with a quick review of the definition of acid and base, consider whether water is an acid or a base, and then work 3 examples of using the equation for pH. It's a base 10 logarithmic scale, where something with pH 5 is 10 times more acidic than something with pH 6. pH7 is neutral, and anything with a pH greater than 7 is considered basic (or alkaline), and anything with a pH less than 7 is considered acidic. Make sure to watch to the end so you can see the surprising pH of some of our everyday liquids! ⬣⬣⬣ LESSON CHAPTERS: 0:00 What is pH? 0:12 Arrhenius definition of an acid - aqueous solutions 1:19 The pH scale 0:42 Bronsted-Lowry definition - doesn't have to be aqueous 1:45 The equation to calculate pH 2:11 Is water an acid or a base? 3:43 The pH scale (0-14) 4:47 pH is a negative logarithmic scale 5:29 Example 1 - lemon juice 6:37 Example 2 - laundry detergent 7:34 Example 3 - soda 8:04 The pH of common liquids SUBSCRIBE so you never miss a video! http://bit.ly/SocraticaSubscribe MORE Chemistry content on our website https://www.socratica.com/subject/chemistry ⬣⬣⬣ SUPPORT our channel: Patreon : https://www.patreon.com/socratica PayPal donation: https://www.paypal.me/socratica Bitcoin : bc1qda47tgfyk67lxa7yqn8y5m02hjcglghsd5c58n Thank you! ⬣⬣⬣ RECOMMENDED Books & Resources: Socratica Practice Tests: https://shop.socratica.com/collections/digital-content How to Be a Great Student: https://amzn.to/3t5jeH3 239 pc Chemistry Molecules Model Kit: https://amzn.to/3DhlG3n Brown and LeMay Chemistry: The Central Science 14th edition: https://amzn.to/3fiLR1G McGraw/Hill Chemistry by Chang & Goldsby https://amzn.to/3UclbP3 Uncle Tungsten: Memories of a Chemical Boyhood by Oliver Sacks https://amzn.to/3ffeRau Napoleon's Buttons: How 17 Molecules Changed History https://amzn.to/3sIXuBW Products in this video: Litmus pH Test Strips, Universal Application (pH 1-14), 2 Packs of 100 Strips - http://amzn.to/2fM8rLo ⬣⬣⬣ Written and Produced by Kimberly Hatch Harrison About our instructor: Kimberly Hatch Harrison received degrees in Biology and English Literature from Caltech before working in pharmaceuticals research, developing drugs for autoimmune disorders. She continued her studies in Molecular Biology (focusing on Immunology and Neurobiology) at Princeton University, where she began teaching as a graduate student. Her success in teaching convinced her to leave the glamorous world of biology research and turn to teaching full-time, accepting a position at an exclusive prep school, where she taught biology and chemistry for eight years. Kimberly co-founded Socratica Studios. ⬣⬣⬣ #Chemistry #pH #EducationalVideo |
