Hello. I am attempting to test kidney stone solubility by using titration methods. I want to set up an experiment that incorporates lemon juice and EDTA solution to dissolve an artificial kidney stone. I need to find a procedure that includes: lemon juice, kidney stone(calcium oxalate), EDTA, and titration methods. Please be as detailed as possible with step-by-step instructions. Thank you.

Investigation of Kidney Stones

To test how long it would take for the calcium phosphate to dissolve in lemon juice.

The most common types of kidney stones are:
Calcium Oxalate: Accounts for 70% of all kidney stones (CaC2O4)

We will synthesize first artificial kidney stones.The procedure is

Calcium Oxalate:

o Dissolved 4.33g of Calcium Chloride (CaCl2) in 10 mL of water

o Dissolved 5.23g of Sodium Oxalate (Na2C2O4) in 10 mL of water

o We then mixed the two aqueous solutions to form a precipitate

CaCl2 (aq) + Na2C2O4 (aq) --> CaC2O4 (s) + 2NaCl (aq)
Net ionic: Ca2+ (aq) + C2O42- (aq) --> CaC2O4 (s)
White precipitate formed, solution was cloudy
Solid calcium oxalate was formed
After Vacuum filtration, centrifuging, and dilution:
2.76g solid calcium oxalate was obtained
Percent yield: 220%

The next step is to dissolve kidney stone.We will use Lemon juice

0.131g CaC2O4 (s) dissolved in 50 mL lemon juice in 30 min.

Hello, I am studying and I am a bit confused about registers. There are segments registers, data registers, pointer registers, index registers. But I do not really understand where these are found. Are they found in 8086 architecture? For instance if I ask what type of registers are found in 8086 architecture what will be the answer? All of these or only segment registers?
