A 13.53 mL sample of 0.05000 M AgNO3 is added to an ion exchange column; the solution that emerges from the other side is found to be acidic. Titration of the solution that comes out of the column requires 22.75 mL of 0.02000 M KOH. a.) How many moles of Ag^+ went into the column? b.) How many moles of H^+ came out of the column?
A studet determined the percentage KHP in an impure sample of KHP . a 3.150g sample of impure KHP required 41.50 mL of 0.1352M NaOH solution for titration.1) calculate the number of moles of NaOH required for this titration
The reaction of benzanilide with Cl2in acetic acid yields a mixture of 2 monochloro derivatives formed by electrophilic aromatic substitution.
Phenol is a common organic compound that may be used as a disinfectant. Its pKa in water is 10.0 while in methanol its pKa = 14.4. Is it a stronger acid in water or methanol? Explain the difference in the pKa for phenol in the different solvents.
Show how you would synthesize the product from the reactant. Show reagents, conditions, and the structures of any important intermediates. Any organic reagent may be used.
