Gout is caused by an error in nucleic acid metabolism that leads to a buildup of uric acid in body fluids, which is deposited as slightly soluble sodium urate (C5H3N4O3Na) in the soft tissues of joints. If the extracellular [Na+] is 0.10 M and the solubility in water of sodium urate is 0.072 g/100 mL, what is the minimum urate ion concentration (abbreviated [Ur - ]) that will cause a deposit of sodium urate?
Enough of a monoprotic acid is dissolved in water to produce a 0.0186 M solution. The pH of the resulting solution is 2.30. Calculate the Ka for the acid.
What us the pH at the equivalence point for the titration of 0.2 M nitrous acid by 0.2 M sodium hydroxide. Ka for nitrous acid is 4.5 x 10^-4
volumetric flask and diluted with deionized (DI) water in order to prepare a calibration standard solution with a concentration of 2.50 x 10-5 M ferroin.
A Solution is prepared by mixing 79 mL of 5.00M HCl and 24.0 mL of 8.00M HNO3. Water is then added until the final volume is 1.00L. Calculate [H+],[OH] and the pH for this solution.
Explain the relationship between the electron configuration and the corresponding principal and angular momentum quantum numbers for each of your elements.
given the pk for acetic acid is 4.76. suppose that we dissolve a mole of this weak acid in 10l of water. find the ph of
A lactic acid/lactate ion buffer solution contains 0.43M HC3H5O3 and 0.62M C3H5O3^-, respectively. The value of lactic acid is 1.4*10^-4. Calculate the pH of this buffer.
First determine the number of moles of rm Na^+ using the given molarity and volume. Next, use the chemical formula to determine the number of moles of rm Na_3PO_4 needed. Finally, convert moles to grams using the molecular weight of the compound.
stable conformation, CH3 at 0,120d, H at 240, then on the other side has H at 0, 120, CH3 at 240d?? and is this a gauche conformation?
Find the mass of AlCl3 that is produced when 25.Og of Al2O3 react with HCl according to following equation Al2O3+6HCl-
how many total moles of gas are produced? B. If each mole of gas occupies 59 L under the conditions of the explosion, how many liters of gas are produced? C. Express your answer using two significant figures. How many grams OF N2are produced in th..
We add excess Na2CrO4 solution to 17.0 mL of a solution of silver nitrate (AgNO3) to form insoluble solid Ag2CrO4. When it has been dried and weighed, the mass of Ag2CrO4 is found to be 0.310 grams.
