We can use evaporation and as well filtration to separate solid to liquid.
When answering the above question or problem, <span>first thing to realize is that the dissolution of the Na3PO4 can be written in a format that may be easier to see what is happening here. </span>
<span>Na3PO4 ----> 3 Na(+) + PO4(-3) </span>
<span>Now, you are starting out with a 0.35 M solution of Na3PO4, but when you dissolve the Na3PO4 into solution there are 3 Na(+) ions made for every Na3PO4 molecule that dissolves. Therefore to calculate the concentration of Na(+) ions in the final solution, take 3 times the inital concentration. 0.35 * 3 = 1.05 M in Na(+)</span>
Hello. Most thermometers would use mercury, but some use alcohol thanks to its freezing points. Alcohol freezes at -114 Celsius, while water freezes at 0 Celsius. If it was freezing outside, the water would freeze too, making the thermometer useless.
