What is the oxidation number of an element and how does it relate to acidity? What is the formula for the conjugate base of HBr? What is the conjugate acid and base of SH-1? What is the conjugate base of HCl? Which is a strong acid? a) HNO_3\b) HNO_2\c) HClO\d) HClO_2 ...
the numerator, and the starting molecule is in the denominator, so if a molecule has a bigger {eq}K_a {/eq}, it will disassociate more in water, creating more hydrogen ions, so a lower pH and more acidic solution. pKa and acidity are intrinsically linked through the equilibrium constant...
pKa and pH - The fundamental distinction between pKa and pH is that pKa denotes an acid's dissociation, whereas pH denotes a system's acidity or alkalinity.
Question: Rank from best acid (low pKa) to worse acid (high pKa). Acid: Acids are the substance that can provide {eq}{{\rm{H}}^{\rm{ + }}} {/eq} ions or receive an electron pair. The reactivity of the conjugate base shares an inverse relation with acid's strength. Lower the...
