Disoluciones tampón - Khan Academy - Crash Course Chemistry

Buffers, the acid rain slayer: In this episode, Hank talks about how nutty our world is via Buffers! He defines buffers and their compositions, talks about carbonate buffering systems in nature, acid rain, pH of buffers, and titration. Plus, a really cool experiment using indicators to showcase just how awesome buffers are. Writers: Kim Krieger & Edi Gonzalez Chief Editor: Blake de Pastino Consultant: Dr. Heiko Langner Director/Editor: Nicholas Jenkins Sound Designer: Michael Aranda Graphics: Thought Cafe

pH y pOH - Khan Academy - Crash Course Chemistry

pH and pOH: In this episode, Hank goes over Reversible Reactions, the water dissociation constant, what pH and pOH actually mean, Acids, Bases, and Neutral Substances as well as the not-so-terrifying Logarithms, strong acids, weak acids, and how to calculate pH and pOH. Oh, and litmus paper! Writers: Edi Gonzalez Chief Editor: Blake de Pastino Consultant: Dr. Heiko Langner Director/Editor: Nicholas Jenkins Sound Designer: Michael Aranda Graphics: Thought Cafe

Acidos y bases - Khan Academy - Crash Course Chemistry

Acid-base reactions in solution: Last week, Hank talked about how stuff mixes together in solutions. Today, and for the next few weeks, he will talk about the actual reactions happening in those solutions - atoms reorganizing themselves to create whole new substances in the processes that make our world the one we know and love. This week, we focus on acids and bases and their proton-exchanging ways.
