Alloys will react negatively: Gold is not effected by nitric acid. Pour a little acid on the dust. Nothing should happen. pure gold weighs 19.3 grams / cubic centimeter. Carefully weigh the dust in grams as accurately as possible. To accurately measure volume, fill a pitcher ( or any container with a spout) with water to overflowing. Then catch the overflow while you pour the dust into the pitcher. Use a graduated cylinder to measure the volume of the overflow. Divide the weight in grams by the volume in cubic centimeters. Within the accuracy of your measurements, the density should be 19.3g / cc. Grandpa It is important to qualify that these tests are for pure gold. Alloys will react negatively:
