How long does it take to grow copper sulphate crystals?
It can take a couple of days.
What can copper sulphate do to a dish if you leave it in room temperature for two days?
it will become a solad
Describe how crystals of copper sulphate are prepared?
You need to start with a copper compound and react it with an acid to get the salt you want. If you use hydrochloric acid you will get a chloride; if you use nitric acid you will get a nitrate. You asked for copper sulphate so can you decide for yourself which acid you need? You will need to put this in a conical flask and heat it - if you're heating acids you must wear protective goggles - and add some copper oxide. This is black. It will react and form a blue solution. You need to be sure you have used up all your acid so you must use enough copper oxide to have some left over. Stop heating and filter it to get rid of the rest of the copper oxide. You want to get rid of the water now - if you want to be quick you can evaporate it by placing it in an evaporating basin on top of a beaker of boiling water. If you have time you can just leave it to evaporate slowly at room temperature. If you do it this way you will get nicer, bigger crystals. Why do you think this is? Look carefully at your crystals to see what shape they are.
How can you filter water from copper sulfate when copper sulfate decomposes when during heating?
You could place the copper sulfate solution in an evaporation dish and let the water evaporate at room temperature over a period of days.
What changes would you observe if you leave a copper sulphate in a room at 21 degrees for 2 days with a lid on the top?
The water from the solution evaporates. A decrease at mass and volume would also occur.
What would happen if you poured 20cm cubed blue copper sulphate solution into a dish and left it at 21 celsius for two days?
u would get a blue waffle

Why is iron pot found to hole after keeping a solution of copper sulphate in it for some days?
Iron is a more active metal than copper, so it replaces/displaces the copper in the copper sulfate, forming iron sulfate and copper. So the hole in the iron pot is where the iron atoms came from. This is called a single replacement/displacement reaction.
A strip of magnesium metal into a solution of copper sulfate?
When we did it the other day what happened was this: the magnesium caused tiny bubbles and little dots of black fell to the bottom of the test tube (Copper I guess). When the reaction stopped, the liquid was still blue. We tried heating the mixture and got a bit more bubbles and 'dots' then we left the test tube for several days. Now the magnesium is coated with a pretty turquise coating of something, the solution is still blue, the dots are still black at the bottom of the tube. So CuSO4 + H2O + Mg should give you MgSO4 (which is soluble) and Cu. I do not know what we have actually got. The chemicals came from a chemistry set...the CaOH was equally not 'right' or rather it was far less 'basic' that I expected hmmm.
What would happen if you leave copper sulphate in a dish with a lid on for 2 days at 21 degrees Celcius?
It will turn brown ish

When Zinc plate was kept in a glass container having CuSO4 examine it found that blue colour of solution is getting lighter After few days when zinc plate was taken out no of holes were noticed?
This because when we place zinc in copper sulphate solution then due to lower reduction potential and higher oxidation potential it consists the ability to loose electrons to copper as copper have more reduction potential (0.34) therefore it gains electrons from zinc. due to transfer of electrons the colour faints and after some days we will see that whole of the zinc gots oxidised and becomes zn2+.

What happens if salt solution is kept for few days?
It could get contaminated, but it should be okay. You can get saline solution for contact lenses that lasts for months, and it's just salt in water.
How long does morphine sulphate ir show up in a drug screen?
up to 4 days
