<p>Our teacher gave us this problem saying it's the kind of question asked on the AP exam:</p>
<p>A student titrates an unknown amount of potassium hydrogen phthalate (KHC8H4O4, often abbreviated KHP) with 20.46 mL of a 0.1000M NaOH solution. KHP (molar mass = 204.22 g/mol) has one acidic hydrogen. What mass of KHP was titrated (reacted completely) by the sodium hydroxide solution? </p>
<p>Thanks!!</p>
<p>any help?? please??</p>
<p>I remember this problem last year from Honors Chem, lol.</p>
<p>Well idk if we're allowed to help on this cause CC say we can't, but it's really not that hard. Remember your steps: make ionic and net ionic equations and use moles from there.</p>
<p>The reason it say KHP has one acidic hydrogen is just to say that it gives off an H+ ion. See if that helps.</p>
<p>Oh, oops I didn't know we weren't allowed to post specific questions... but your advice DID help. Thanks.</p>
