Text Solution

Verified by Experts

The correct Answer is:

Although Na K are almost equally abundant in the earth's crust, yet sea water contains 2.8% NaCl but only 0.8 % KCl because much of K appearing in group water from dissolved minerals is taken up preferentially bu plants while Na goes to the sea water.
