Uncertainty in Measurement (Section)
You have a graduated cylinder that contains a liquid (see photograph). Write the volume of the liquid, in milliliters, using the proper number of significant figures.
Organic Chemistry 1, Prof. Strongin, CH 334 section 1, Fall 2017 Chapters 6 & 7: Bronsted acid: A proton donor ex: HCl, H2O Bronsted base: A proton acceptor Conjugate acid: The molecule that results upon protonating a base Conjugate base: The molecule that results upon deprotonating an acid Proton transfer reactions are typically fast and reversible and thus are drawn as equilibrium with two arrows Pka is the unit measure for acidity - Low Pka = more acidity. - Pka = -log ka - Ka = [H2O] Keq The larger the value of equilibrium constant the more products formed Keq and Pka are inversely related When Pka = PH an acid is 50% dissociated in water The stronger the acid the weaker conjugate ba
