Density

Hi! I am sure everybody knows or heard of the dead sea before and of its strange ability to allow the personn to float on the sea. The reason behind this is pretty simple: The dead sea has very low concentration of sulfate ions (SO24) and the highest concectration of bromide ions. Its salt levels are also the highest on the planet. All of these factors added would cause the unusual low density of the sea. To put it simply, try out this example . Firstly, prepare a bowl of water at a depth of the width of an egg. Place an egg in the water. Observe if the egg floats or sinks. Next, add a generous amount of salt into the water and stir till the alt dissolves. You will observe that the egg floats after you add salt. I am sure you would have known why people can float on the dead sea. Bye!
