1. Calcium phosphate has a Ksp of 2.07x10^-33. Determine:
a) The molar solubility of calcium phosphate.
b) The molar concentration of calcium ions at equilibrium.
c) The molar concentration of phosphate ions at equilibrium.
2. The Ksp of magnesium hydroxide is 2.06x10^-13. You may disregard the normal hydroxide concentration in water
a) What is the molar solubility of magnesium hydroxide?
b) Based on your solubility what is the pH of the resulting solution.
c) Without doing any additional calculations, will magnesium hydroxide be more or less soluble if it is in a solution that is buffer to pH 7.5.
You have samples of approximately 8mL solution with ph ranging from 4 to 10. Calculate the volume of 1M HCIO4 needed to lower the ph to 2.5.
Calculate the amount of N2 gas released (in liters at 37° C and 1.5 atm) when the diver returns to the surface of the water, where the partial pressure of N2 is 0.80 atm.
Determine the subunit composition of this protein from the following information: 10 points Molecular mass of the native proteinby gel filtration is 300 kD Molecular mass by SDS-PAGE
The biochemical oxygen demand (BOD) is the capacity of organic and biological matter in natural water to consume oxygen. It is determined experimentally by measuring the oxygen concentration in a sealed sample before and after a 5-day incubation p..
Consider a cylinder filled with air with a piston and spring arrangement on top. The external pressure is 1 bar, the initial temperature of the air in the cylinder is 25 C.
