# How can the density of water be maximised?

What is the maximum possible density of water at room temperature? The density of the water in the Dead Sea at 37°C is 1.24. Would it be possible to increase the density using salts we add to our food, or possibly by using different salts than are present in the sea?

• I believe in your first sentence is a temperature too much and a density missing. What do you mean with homesalts? And I do not understand what "... and bringing some from out?" means. Could you please take a look and make your question a little clearer. Thank you. Jul 17 '14 at 10:01
• True. What I meant was what salts could I use to increase the density would the salt that we add in food work or wel have to add the diffetent salts present in the sea. Jul 17 '14 at 11:55

Sodium polytungstate $\ce{Na6[H2W12O40]}$ is a relatively safe compound and allows densities up to 3.1 g/ml. $\ce{ZnCl2}$ allows densities up to ~ 1.9 g/ml, but has acidic solutions.
