Denaturation of Protein by Strong AcidJohn W. Moore, Jerrold J. Jacobsen, Gary Trammell, Kristin Johnson "Strong acid denatures egg white proteins.This video contains voiceover:""The tertiary structure of egg white proteins is held together by hydrogen bonding and hydrophobic interactions. Adding strong acid to the protein disrupts the intermolecular forces, and the tertiary structure is lost. The loss in protein structure is called denaturation. The proteins precipitate, forming a white solid."""
Extraction of Acid with Base Water and diethyl ether are shaken in a separatory funnel with a small amount of red indophenol. The non-ionic indophenol remains in the ether layer, coloring it red. Addition of sodium hydroxide converts the indophenol to its blue ionic acid anion which is extracted into the water layer turning it blue.
Reactions : AcidBaseRxns (20 Variations) In order to answer the following questions, write the net ionic equation for the reaction between equal volumes of 0.10 M solutions of the following acid and base:
KOH(aq) + HBr(aq)
What are the reaction products? Does the reaction yield an acidic, basic, or neutral aqueous solution?

The Correlation of Binary Acid Strengths with Molecular Properties in First-Year ChemistryTravis D. Fridgen This article replaces contradictory explanations for the strengths of different binary acids in first-year chemistry textbooks with a single explanation that uses a BornHaber cycle involving homolyic bond dissociation energies, electron affinities, and ion solvation enthalpies to rationalize trends in the strengths of all binary acids. Fridgen, Travis D. J. Chem. Educ.2008, 85, 1220.

An Inexpensive Solution CalorimeterEmma Kavanagh, Sam Mindel, Giles Robertson, and D. E. Peter Hughes Describes the construction of a simple solution calorimeter, using a miniature bead thermistor as a temperature-sensing element, that has a response time of a few seconds and made it possible to carry out a thermometric reaction in under a minute. Kavanagh, Emma; Mindel, Sam; Robertson, Giles; Hughes, D. E. Peter. J. Chem. Educ.2008, 85, 1129.
Acids and Bases (Netorials)Rachel Bain, Mithra Biekmohamadi, Liana Lamont, Mike Miller, Rebecca Ottosen, John Todd, and David Shaw Acids and Bases: this is a resource in the collection "Netorials". In this module there is an introduction to the chemical properties of acids and bases. Afterwards, the sections include topics such as Molecular Structures of Acids and Bases, Ionization constants, properties of salts, buffers and Lewis theory of Acids and Bases. The Netorials cover selected topics in first-year chemistry including: Chemical Reactions, Stoichiometry, Thermodynamics, Intermolecular Forces, Acids & Bases, Biomolecules, and Electrochemistry.

Strong Acids (GCMP)David M. Whisnant Strong Acids: this is a resource in the collection "General Chemistry Multimedia Problems". This problem will explore the properties of common strong acids. General Chemistry Multimedia Problems ask students questions about experiments they see presented using videos and images. The questions asked apply concepts from different parts of an introductory course, encouraging students to decompartmentalize the material.
Acids / Bases
Acids and Salts (GCMP)David M. Whisnant Acids and Salts: this is a resource in the collection "General Chemistry Multimedia Problems". This problem will explore a few properties of common acids and their salts. General Chemistry Multimedia Problems ask students questions about experiments they see presented using videos and images. The questions asked apply concepts from different parts of an introductory course, encouraging students to decompartmentalize the material.
