CHEM 1C Lecture Notes - Lecture 8: Litmus, Chemical Equation
Document Summary
This is the link between the equilibrium constant, k, for any change and the standard reaction free energy, (delta)g(rxn) K increases with increasing t if (delta h) is + K decreases with increasing t if (delta h) is - Acids have a sour taste, dissolve many metals, turn blue litmus paper to red, and neutralize bases. Bases have a bitter taste and a slippery feel, turn red litmus paper to blue and neutralize acids. Acids are substances that produce h+ ions when dissolved in water (aqueous solution) Bases are substances that produce oh- ions when dissolved in water. Ka is the acid dissociation constant (only found out through aqueous solutions and its products over reactants) Conjugate acid-base pairs: conjugate acid bare pairs consist of two substances related to each other by the donating and accepting of a single proton. If it has the proton (acid) and if it loses it " then it is the base.
