CHM 1430 Study Guide - Final Guide: Acid Dissociation Constant, Molar Concentration, Chemical Equation
Document Summary
1 ph unit represent a _______ inc or dec. In pure water at 25 degrees c kw= 1. 0 x 10^-14 poh= 7 ph= 7 and [h3o+] = [oh-] =[h+] Big ka means strong acid big ka means a ____ pka small small pka means stronger acid (bigger ka) big pka weak acid (small ka) As ka increases pka decreases to find the ka given pka. [h+]= sqrt (ka/[ha molarity]) to get [h]+ when given ph you must. H3o+/h+ strong conjugate base has a weak acid if given a kb value and it is asking for the ph you need to find _____ Ka by using this equation (ka x kb = kw) Strong acid + weak base = _________ solution acidic salt. Strong acid + strong base = _________ solution neutral salt weak acid + strong base = _________ solution basic salt a stronger base will have less h+ a stronger acid will have more.
