Formic acid, HCHO2, is a weak electrolyte; What are the solute particles present in aqueous solution of each compound?
Constant-boiling HCl can be used as a primary standard for acid-base titrations. A 50.00 mL sample of constant-boiling HCl with a concentration of 0.1193 M was collected and titrated to an end point with 34.89 mL of Ba(OH)2 solution. What is the m..
A 9.1 g sample of C6H5NH3Cl is dissolved in water to make 346 mL of solution. Determine the percentage deprotonation of the cation.
Assume that a solid has a constant of Cp,m=25 J/K-mol from 50K to 298K and that the DeBye approximation is valid from 0K to 50K. Estimate the standard molar entropy Sm for the solid at 298K.
