While 760mm of Hg is taken 1atm pressure was measured. Explain what will be the height of the barometric column if this mercury is replaced by water?
What is the expected pH of this solution. Estimate the free carbonate ion concentration in this solution. Estimate the concentration of carbonic acid in solution.
Citric acid, found in citrus fruits, is a triprotic acid, H3C6H5O7. Write the Chemical equations for the three-step ionization of this acid in water and write the three Ka expressions (equilibrium laws)
upon catalytic hydrogenation unknown Z gives cyclooctane. Oxonolysis of Z followed by reduction with dimethyl sulfide, gives a three0carbon dialdehyde and a five-carbon dialdehyde. Draw the stucture of Z.
What is the approximate pH of a solution prepared by adding 20 mL of 0.10 M NaOH to 200 mL of 0.10 M HCl?
Calculate the molar solubility of AgBr in 4.0 M NH3. Kf for Ag(NH3)2 is 1.7 x 10^7 and Ksp for AgBr is 5.0x10^-13 5. What is the pH at the equivilaence point when 45 mL of 0.125 M acetic aced is titrated with 0.225 M NaOH? Ka for acetic acid is 1.7..
