I presume that, by "the liquid", you mean copper sulphate solution.
If so, the liquid will slowly turn from blue to colourless: you'll finish up with a solution of magnesium sulphate and the copper will precipitate out as a brown powder.
Chemically, what will have happened is that magnesium, being more electropositive than copper, will displace the copper. Another way of putting it is that the magnesium donates two electrons to the copper ions:
Mg(s) + Cu++(aq) → Mg++(aq) + Cu(s)

Magnesium Copper Sulphate

Answer - new solution will be magnesium sulphate.
All metals have different reactivities, some react easier than others. The metals can be placed into a reactivity series that can be used to predict reactions.
eg. potassium, magnesium, iron, copper, gold would be a simple reactivity series with potassium the most reactive and gold the least reactive.
In your experiment a more reactive metal will displace a less reactive metal from its compound. So magnesium is more reactive than copper so it displaces the copper from its compound and is replaced by the magnesium. The reactions are often identified by a change in colour of the solution or a temperature change. In your experiment the blue copper sulphate will change into clear magnesium sulphate.

RE:
when magnesium is added to copper sulphate the liquid turns to what?

Mg (s) + CuSO4 (aq) ---> MgSO4 (aq) + Cu (s)
The silver magnesium will react with the blue copper sulphate solution to form a colourless magnesium sulphate solution and reddish brown copper powder.
This is because magnesium is more reactive than copper.

With every day pass, our country is getting into more and more trouble. The inflation, unemployment and falling value of dollar are the main concern for our Government but authorities are just sleeping, they don’t want to face the fact. Media is also involve in it, they are force to stop showing the real economic situation to the people. I start getting more concern about my future as well as my family after watching the response of our Government for the people that affected by hurricane Katrina.
According to recent studies made by World Bank, the coming crisis will be far worse than initially predicted. So if you're already preparing for the crisis (or haven't started yet) make sure you watch this video at http://www.familysurvival.tv and discover the 4 BIG issues you'll have to deal with when the crisis hits, and how to solve them fast (before the disaster strikes your town!) without spending $1,000s on overrated items and useless survival books.

Now everyone can cure infertility using this natural remedy http://pregnancyhelps.info
infertility can run in the family and one of the first things the doctor asks you when you go to a fertility clinic is your family history regarding cases of infertility or other reproductive issues.
If infertility is caused by genetic disorder then it's not unusual that one of the kids (your mom) doesn't have it and another does (your aunt).
two months of trying is still to early to be concerned about the fact that you might be infertile and it's also quite early to go to a fertility specialist. Go to a regular Obgyb to get a closer insight and see what ways there are are to improve your fertility rate.
Also remove alcohol, caffeine and cigarettes from your life because they might influence your chances too. Stress is also a risk factor when it comes to infertility.
