<p>Important Stuff for Acid/Base or Solubility(FRQ1)</p>

<p>Henderson HasselBach Equation: ph = pKa + log[(A)/(HA)]</p>

<p>Molarity/Volume Equation: M1 x V1 = M2 x V2</p>

<p>Have to remember to make sure M is in moles/Liter and V is in Liters
pkA is log(Ka)</p>

<p>Ka is acid constant (conc. of products over reactants)
Kb is base constant (conc. of products over reactants)
Ksp is solubility product</p>

<p>I know I learned more stuff about Acid Base Titration and Solubility stuff, but I seem to have forgotten, if anyone else remembers anything else for Titration/Solubility feel free to post :)</p>

<p>Ka * Kb = 10^-14
pKa = -log(Ka)
pH + pOH = 14
Molarity = n/L</p>

3

<p>[H][OH] = 1 x 10^-14
Buffer - Combination of weak acid and its conjugate base that resist changes to pH.
Bronsted Lowry Defenitions - ???
Arrehenius = Acid - Gives off H+ , Base - Gives off OH-</p>

4

<p>Bronsted acids donate H+, Bronsted bases accept H+</p>

<p>Lewis acids accept electron pairs, Lewis bases donate electron pairs</p>

<p>Hey, shouldn’t you be doing some last minute cramming instead of posting on CC?</p>
