What does photometric titration entail?
Consider the equilibrium in water – hydrogen – oxygen system. If it is desired to operate the system so that the partial pressure of oxygen will be 1x10^10 atm. What should be the ratio of hydrogen to water vapor needed to achieve this condition at 2000K?
You may expect _____ bonds between two atoms which each have a valence of 1 or 2
What will be the titration curve and pH for titrating 0.2 M acetic acid with 25 ml 0.2 M of NaOH.
For calibration of 10 ml at 23 degree centigrade a 10 ml liquor of water is weighted by analytical balance which is 9.9367 g. Calculate the actual transferred volume. If the density of water at 23 degree centigrade is 0.99754 g/ ml.
A compound containing only carbon, hydrogen and oxygen was analyzed by combustion analysis. Combustion of a 10.68 g sample of the compound in excess oxygen gives 16.01 g CO2 and 4.37 g H¬2O. The molar mass of the compound is between 170 and 180 g/mol. What is the molecular formula of this compound?
