Answer :
The given statement is false because if the spike was assigned bc, then he can not combine 8.00 ml of ammonium chloride and 4.00 ml of ammonia to make his buffer.
A buffer is a solution that can resist changes in pH when small amounts of acid or base are added to it. It consists of a weak acid and its conjugate base, or a weak base and its conjugate acid.
The buffer system consisting of ammonium chloride and ammonia requires specific concentrations of each component to maintain a stable pH. Simply combining 8.00 mL of ammonium chloride and 4.00 mL of ammonia may not necessarily result in the desired pH buffer solution. The actual concentrations required will depend on the desired pH of the buffer solution.
Therefore, additional calculations and adjustments may be necessary to prepare an effective buffer solution.
