Answer:
Neutralization is when the pH (power of hydrogen ions) of a solution is at 7 (considered neutral in the pH scale). This means it's neither acidic nor basic and is neutral. In order to neutralize an acidic solution, you pour in the same amount of a strong base. And in order to neutralize a basic solution, you pour in the same amount of a strong base.
A neutralization reaction will give you salt and water. A common neutralization reaction could be:
HCl (strong acid) + NaOH (strong base) ----> NaCl (Salt) + H2O (water)
Determining the volume of water displaced by the crown and using the gold density to determine the mass of the crown equals the mass got from weighing the crown on a weighing machine. if the mass matches the mass got from the weighing machine then the crown is made of pure gold if otherwise, the gold is not pure.
