Question

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 the samples after they are collected?
(1 point)
use a hydrometer to measure salinity
use wide litmus paper to determine the acidity
use a turbidity meter to calculate light transmission
use an atomic absorption spectrometer to detect elements and compounds

Explanation:

Atomic absorption spectrometry is a technique used to detect trace metals. A hydrometer measures salinity (not trace metals), litmus paper determines acidity (not trace metals), and a turbidity meter measures light transmission (not trace metals). So the most appropriate tool for detecting trace metals (elements) in seawater is an atomic absorption spectrometer.

Answer:

use an atomic absorption spectrometer to detect elements and compounds
