Potassium hydrogen phthalate is a monoprotic acid. Dihydrogen pthalate (H2C8H4O4) is a diprotic acid. An analyte sample contains 0.127 M KHP and 0.0678 M (H2C8H4O4). What volume of a 0.205 M NaOH solution is required to neutralize 25.0 mL of the analyte solution.
Identify each of the following substances as an element, compound, solution, or heterogeneous mixture
0.80g of hydrogen chloride is dissolved in water to make 2.5L of solution. What is the pH of the resulting hydrochloric acid solution?
How many moles of HCl must be added to 1.0 L of 1.0 M NH3(aq) to make a buffer with a pH of 9.00? (pKa of NH4^+ = 9.25)
Humans consume glucose, C6H12O6, to produce engery. the products of glucose consumption are CO2 and H2O. C6H12O6(s)+6O2(g)--->6CO2(g)+6H20(g)
Consider a chromatogram containing a single analyte with retention time of 4 minutes. The mobile phase elution time is 0.2 minutes. What is the capacity factor (k') for the analyte in question?
The unit of S was the J/(mol*K) the book said. But, in delta S, why the unit is J/K? I just think when I want to calculate delta S, sum of products's S - sum of reactants's S, so the unit of delta S is same as S I thought. What is it
Suppose that 0.680 mol IBr in a 2.50-L flask is allowed to reach equilibrium at 150.°C. What are the equilibrium concentrations of IBr, I2, and Br2? [Br2] ?? M [I2] ?? M [IBr] ?? M
