The local anaesthetic lidocaine is required by the British Pharmacopoeia to contain not less than99.0% and not more than 101.0% of C14H22N2O, calculated with reference to the anhydroussubstance.0.2093 g of a lidocaine sample was dissolved in anhydrous acetic acid and titrated with 0.1025 Mperchloric acid. 8.53 mL was required. Another sample of the lidocaine from the same batch wasfound to contain 0.78% water. Does the sample meet the BP requirements?

2. The addition of dimethylglyoxime, H₂C4H6O₂N2, to a solution containing nickel(II) ion gives rise to the precipitate, Ni(HC4H6O₂N2)2: N₁²+ + H₂C4H6O₂N₂ → 2H+ + Ni(HC₂H5O₂N2)2 (s) Nickel dimethylglyoxime is a bulky precipitate that is inconvenient to manipulate in amounts greater than 175 mg. The amount of nickel in a type of permanent-magnet alloy ranges between 24% and 35%. Calculate the amount of sample that should not be exceeded when analyzing these alloys for nickel.
