What volume (in liters) of 0.94 M KOH solution should be added to a 0.090 L solution containing 9.1 g of glutamic acid hydrochloride (Glu, FW=183.59; pka1=2.23, pka2=4.42, pka3=9.95) to get to pH 10.20?

Tungsten trioxide (WO3) has a rich yellow color and is often used as a pigment in ceramics and paints. In order to test a ceramic vase for its WO3 content, a 10.19 g sample of the vase was ground and reduced with Pb(Hg) to convert any WO3 to W3 . The resu...

Not initially. Sapling learning says "Glutamic acid can act as a buffer at each of its three pka values. To solve this problem, you need to take into consideration the amount of KOH that must be added to the glutamic acid solution to move the pH through i...

I found that there are .04956 moles of KOH. Are you saying that there are 1.04956 moles total including the neutralized H? From there is the log "ratio" simply that number?

I calculated .04956 moles of Glutamic acid and a total of (twice as much) 1.877 moles of KOH needed. Using the pH given, the pKa3 for the HH. How do I solve for the liters from there?

i solved for x and got x=.03175 moles. Do I simply divide that by .94moles of KOH to get liters?

I divided that by .94 moles and got .03377L and added that to .0527L of the first two parts to give a total of .086L total. Which was still marked incorrectly. What am I doing wrong?

I know, i'm sorry. Thanks for all of your help!!!
