State whether the following are true or false.
Sea water is the purest form of water.
Seawater contains certain following impurities. The two ions that are present most often in seawater are chloride and sodium. These two make up over 90% of all dissolved ions in seawater. The concentration of salt in seawater (its salinity) is about 35 parts per thousand.
For the above reason, seawater is not the purest form of water. Hence, the given statement is false.
