Determine the following characteristics of the titration curve for 25.0 mL of 0.400 M NH3(aq) titrated with 0.335 M HI(aq). (For NH3, Kb = 1.8x10-5.) Enter scientific notation as 1.23E4. (a) The initial pH : Enter only numbers in your answer. (b) The volume of HI(aq) required to reach the equivalence point : (c) The pH at the half-neutralization point. Enter only numbers in your answer. (Do not include units.) (d) The pH at the equivalence point.
camphor is a chiral compound and exists as two enantiomers. we are using a racemic mixture of both enantiomers. however,we draw the structure of only one enantiomer.
