Some researchers have hypothesized that there could be trace metals in sea water. To test this hypothesis, they collect samples of sea water. What will they MOST likely do with samples after they are collected?
A: use a hydrometer to measure salinity
B: use water litmus paper to determine the acidity
C: use a turbidity meter to calculate light transmission
D: use an atomic absorption spectrometer to detect elements and compounds
D: use an atomic absorption spectrometer to detect elements and compounds
D: use an atomic absorption spectrometer to detect elements and compounds
To determine if there are trace metals in sea water, researchers would most likely choose option D: use an atomic absorption spectrometer to detect elements and compounds.
An atomic absorption spectrometer is a scientific instrument used to measure the concentration of elements in a sample. It does so by passing light of a specific wavelength through the sample, and then measuring the amount of light that is absorbed by the sample. This method is commonly used to detect and quantify trace metals in various substances, including sea water.
After collecting the samples of sea water, the researchers would likely take those samples to a laboratory equipped with an atomic absorption spectrometer. They would carefully prepare the samples for analysis, following established protocols to ensure accurate results. Then, they would use the atomic absorption spectrometer to analyze the samples and determine the presence and concentration of trace metals in the sea water.
Therefore, option D is the most appropriate choice for testing the hypothesis of the presence of trace metals in sea water.
