Which of the following compound is the most abundant compound in sea water?
a.
NaCl
b.
CaCl
c.
LiCl
d.
KCl
The most abundant compound in sea water is option a. NaCl (Sodium Chloride)
To determine which compound is the most abundant in sea water, we can look at the composition of sea water and compare the concentrations of these compounds.
The most abundant compound in sea water is sodium chloride (NaCl), which is commonly known as table salt.
One way to determine this is by looking at the average salinity of sea water, which is approximately 3.5%. This means that for every 1000 grams of sea water, there are approximately 35 grams of salt.
Calcium chloride (CaCl) and lithium chloride (LiCl) are present in sea water, but in much smaller quantities compared to sodium chloride.
Potassium chloride (KCl) is also present in sea water, but its concentration is even smaller than calcium chloride and lithium chloride.
Therefore, the most abundant compound in sea water among the options given is sodium chloride (NaCl), which makes option a the correct answer.
