Want this question answered?
rock salt is actually salt and not any type of rock. large size salt crystals are reffered to as rock salt because it is hard like rocks. its actually jsut large salt crystals. if you are looking to purify your salt you could always heat a pot of water and disolve the rock salt in it. once no more salt will desolve you can decant the salt water (poor the clear liguid off leaving behind the other stuff) into another pot leaving behind the impurities. then boil the salt water to evaporate the water leaving behind the pure salt crystals. Actually, the way to do it is. First mix the rock salt with water. The salt will dissolve and the rocks will stay. Filter it and the salt water will go through. Evaporate it and the salt will be left.
The larger the potato, the longer it will take to bake, but the average time is about 30 minutes to an hour at 350 to 400 degrees. Wrapping the potato in foil will allow the heat to stay in the potato better.
Osmosis will happen. The water will move from the potato into the sugar solution. The potato will lose mass and shrink.
when an oven is on bake the oven stays on all the time till you turn it off. On T-bake or Timed bake the oven will stay on when whatever amount of time you have set elapses the oven will turn itself off.
